This is defnitely kind of cool, but I will be a great deal more impressed when it is achieved with an object with appreciable mass. This said, it does seem to show me the way to cut down my lag to that Counterstike server - all I need is a fibreoptic modem!

Light Particles Are Duplicated More Than a Mile Away Along Fiber
By KENNETH CHANG
Employing a facet of quantum mechanics that Albert Einstein called "spooky action at a distance," scientists have taken particles of light, destroyed them and then resurrected copies more than a mile away.
Previous experiments in so-called quantum teleportation moved particles of light about a yard. The findings could aid the sending of unbreakable coded messages, which is limited to a few tens of miles.
The new experiment used longer wavelengths of light than earlier ones, letting the scientists copy the light through standard glass fiber found in fiber optic cables.
"The central issue is to move to telecom fibers and telecom wavelengths and telecom technology," said Dr. Nicolas Gisin, a physics professor at the University of Geneva and the senior author of an article today in the journal Nature. "This then allows us to go the long distance."
The experiments are a primitive realization of the transporter in the "Star Trek" television series that beams people from starship to planet. In coming years, it may be possible to use teleportation to imprint the exact quantum configuration of one atom to another. But teleporting something from the everyday world like a person that contains more than a trillion trillion atoms is highly unlikely, if not impossible.
Even with the light particles, photons, about one in a thousand were received at the other side.
"You're not very sure to arrive," a researcher, Dr. Hugo Zbinden, said about human teleportation.
Still, the experiments show that scientists can overcome a seemingly insurmountable conceptual barrier, the Heisenberg uncertainty principle. The principle states that the location and velocity of a particle cannot both be precisely measured at the same time. That would seem to make it impossible to teleport anything, even single particles, because without knowing their exact specifications they cannot be copied somewhere else.
Devised in 1993 by scientists led by Dr. Charles H. Bennett of the I.B.M. Thomas J. Watson Research Center in Yorktown Heights, N.Y., quantum teleportation produces pairs of "entangled" light particles that can be thought of as a pair of encoding and decoding rings. A message is combined with the encoding light particle. That combination goes to the recipient, who uses the decoding photon to decipher the message. Because no one else has the decoding photon, no one else can decipher the message.
Other encoding techniques using quantum cryptography are simpler, and a more immediate use for teleportation would be as a repeater. Photons almost all peter out after traveling about 50 miles through optical fiber. Teleportation would enable the creation of copies every 50 miles or so, letting the message be sent across an unlimited distance.
I could have swong this was done several years ago. Personally it seemd a lot like the disassembly and reassembly of a web page to me.
Never really got what was supposed to be so amazing...
teleport your ass over here and get a reg free link
Does this have anything to do with quantum pairs, where changing one particle causes the exact change in its mate, instantaneously, no matter how far apart they are?
Hookers on demand....the porn/sex industry is going to be the first in line if they can ever get matter to teleport correctly...even if they don't i wouldn't mind having hooker with 3 breasts =]..
The potential application of this technology is boundless. Everything from communication to transportation, even society will be changed by the refinment and eventual mastery of this particular branch of quantum physics.
I'm sure 400 years from now people will be using spooky action at a distance to teleport to their flying cars so they can head out to stores to finally buy a shrinkwrapped copy of Duke Nukem Forever.

Teleporting an object with considerable mass - ok
NOT me though. What do you think might happen to you between the time you are destroyed and the time your mass is replicated?
I would think that even if it were a very short time there would still be problems -- after all you WERE destroyed.
On the good side - imagine a future when you can purchase something online and have it in 5 min. by replicating it in your new replicator(duh) thats connected directly to your computer. You buy the item - then download the mass profile(perhaps a

Nothing better than reading an interesting article which contains absolutely no scientific information... What was the emitter? What was the detector? How were the photons "destroyed"?

I'm still waiting for a cloned sheep to be teleported into my bathtub. By the Raelians.
If teleporting a human requires making a copy and destroying the original, then the obvious question is: is the copy still me? This raises the interesting question of what exactly constitutes personal identity. Here is a very entertaining and amusing read on the topic by Daniel Dennet, a first-rate philosopher and all-around funny guy.
From the article: "quantum teleportation produces pairs of "entangled" light particles that can be thought of as a pair of encoding and decoding rings. A message is combined with the encoding light particle. That combination goes to the recipient, who uses the decoding photon to decipher the message. Because no one else has the decoding photon, no one else can decipher the message." First question. Does it mean that we can somehow store that information being transmitted and reproduce it again and again, something like copying?? Wow, that would a new form of cloning... me and my evil copies will rule the earth(if we don't get on each other's nerves first that is). If not, so all I need is a hacker of some kind. Maybe he wont be able to decipher what he captured, but hey, for me it would probably mean being teleported without a head or smething. Not very interesting for aesthetic point of view I will say
What's under yellowstone?
Customer: "But it doesn't work."
Salesman: "That is the state of the art..."
To be honest, I wasn't aware there was any base in teleportation from which to improve.

How do they know it's the same electron? What distinctive marks are they basing this on? If it's just one electron that disappears and another one that reappears, the applications would be rather more limited. I mean, if I step into a teleportation machine, I would quite like me rather than someone who looks just like me to step out a mile away.

My point? It is one thing to teleport a photon, which is a massless boson. It is quite another thing to teleport a massive fermion, let alone a collection of them as would be found in any massive object of appreciable size. The physics of teleportation would most likely be very different, since the quantum mechanics and statistics of bosons are quite different from those of fermions. So don't get your hopes up yet regarding teleportation a la Star Trek.
Due to cloning laws and all that, isn't teleportation of people illegal ? by the process of copying someone and probably deconstructing them could be considered murder ? Oops...
--- Did I say that ?
Just to be pedantic... The Heisenberg Uncertainty principle does not just state that we cannot know both the velocity and position of an object, but that neither really exist independently until we measure them. Then measuring one effects the other.
If we measure an object's velocity 100% perfectly, then it no longer has a definite position.
Is that cool or what?
Unfortunately, I am not Wil Wheaton
No, this is not a form of Star Trek's Heisenberg Compensator. The whole point of Heisenberg Uncertainty is that it is fundamental and unavoidable. You can get down to that magic h-bar/2pi, but no further. Period.
...
If you could get around that uncertainty issue, it would blow away quantum cryptography entirely; the beauty of it from a security standpoint is that any eavesdropping can be detected, because observing the qubits (in this case, photons with particular spin) necessarily disrupts a certain portion of them.
Yes, this means that a determined eavesdropper could mount an effective DoS by reading all the bits, but with that kind of access, there are easier ways. (Uh, how about cutting the fiber?)
And it's not really teleportation. It's still fundamentally limited to the speed of light. "Teleporting" anything more complicated than a hydrogen atom is going to be insane due to (here it comes again) Heisenberg Uncertainty - you have to extract its state, but you can't do that to within that certain magic tolerance
I can just imagine all the boffins pacing around the lab trying to decide who will be the first to test the new mass trasporter.

Just think... we'll never have to complain about crazy teleporters cutting us off on the way to work again. Or potholes, I hope. ("Sorry I'm late to work, I hit a pothole while teleporting.")
Now if this data was released just a little earlier, Bush could have addressed this in the State of the Union, rather than something as "old school" as hydrogen-based vehicles. Like those will ever see the light of day!
Ok, before everyone freaks, Quantum Teleportation isn't what most think it is. I've had a class and attended a few lectures by renowned Gilles Brassard from the University of Montreal, one of the founder of the field and especially quantum encryption, along with Charles H. Bennet from IBM and many others.

First, "teleportation" only teleports "DATA", quantum information, like the spin of an electron. You won't see any beam me up scotty, despite how much people wants to and how wrong reporters are in artciles =)
Second, here's a VERY brief info page on Quantum Teleportation on IBM's page:
http://www.research.ibm.com/quantuminfo/telepor
For more in depth info, try to find articles in magazines and books, especially one written by Charles H. Bennet and/or Gilles Brassard.
One lecture by Brassard can be found online here, there's even a PDF:
http://www.msri.org/publications/ln/msri/2002/q
They will explain this much better than my understanding will do. It's MUCH funnier and interesting when Brassard presents it, and it's MUCH harder to understand too. The few pictures and bits at the begining of the lecture are what Quantum Teleportation is NOT. Even renowned scientific publication are fooled by bad journalism, and even IBM went over it's head with this, it's kinda funny =)
Anyway, "Beam me up Scotty" will never result from Quantum Teleportation, so don't hold your breath =) The article briefly states this tho, but only seems to gloss over it and even says "maybe", which is completely wrong.
Also, Brassard stated MANY times that is does not violate ANYTHING, and especially not Heisenberg uncertainty principle. The original DATA must be destroy, then it is "rebuilt" on the other side, and because of a property of EPR, "entanglement", you never mesure the quantum information completely, thus not violating Heisenberg uncertainty principle.
One last note, the following bit on the article is probably the most simplistic non-explanation of what is Quantum Teleportation:
"A message is combined with the encoding light particle. That combination goes to the recipient, who uses the decoding photon to decipher the message. Because no one else has the decoding photon, no one else can decipher the message."
Most of the comments I see are about replicating objects, so I thought I'd throw this out there. The true use of this technology will be for data replication. They are nowhere near being able to "transport" objects as many of the star trek references imply. However, they are learning how to replicate data fairly quickly. Ie, you have a set of atoms, etc, containing your companies financial records and each change in that set of atoms is immediately replicated in another set at some other location, thus providing failover backups of critical data.
Now I just have to sit and wait for them to come out with a comercial version of a tele-magic 9000. I could find about a thousand uses for the thing. Running marathons in under a nanosecond, teleport myself straight into a MGM Grand vault, go to Jamaica for lunch...I'm getting dizzy, better stop.
"Make me some if you're making some"
Not quite. That's more like a 'hidden variable' version of Quantum Mechanics. The box that the poison treat is in is a hidden variable because it has a definite value (albeit unknown to you). The standard interpretation of Quantum Mechanics is that there are no hidden variables. So the poison treat would have to be simultaneously 'in both' and 'not in both' boxes until you observe one of the cats.
The original Schroedinger's Cat thought experiment used a truly quantum-mechanical device to determine whether the cat should live or die. I don't think you can remove that quantum element and still have a valid analogy. The point (or one of them) of the thought experiment is that the cat 'magnifies' the quantum effect.

A whole new definition of the term vaporware?
well, two entangled particles can be considered to be a single entity; and the second particle cannot exist indefinitely without the destruction of the original particle; and 'I' can be considered to be a collection of particles, neurons etc etc :: then assuming there is one day a way to entangle trillions of trillions of particles it could one day be possible to transport, yes? and i would never really be considered to have been destroyed or copied, becuase there was only ever really one me during the entire process.
1. Build a quantum teleportation device :)
2. Find something to teleport (probably a slashdot moderator)
3. Test out teleporter with horrible results (sorry Taco
4. Refine teleporter
5. Have teleporter confiscated by homeland security.
6. PROFIT!!!!!!!!
I'm curious - just how practical is this going to be in terms of the power required? Is this going to be one of those things that takes so much power consumption to work on a large scale that it's impractical?
You call this a signature?
so if you can send light over distances, that is cool for signal transfer without wires and/or need for a line of sight...
but this is still pretty worthless in terms of sending people around (and turning them into half man half fly mutants).
There are some odd things afoot now, in the Villa Straylight.
This technique uses quantum entanglement which says that two qbits naturally form "pairs" that can be moved apart and retain their orientation to each other. You would then pick up a matching qbit on the other side which would cause the former match to pick up something else instantly (or be converted to some kind of energy). At quantum levels to read the information is to destroy it. Extreme, but the fundamental point of the Heisenburg principle. As soon as a particle is "read" it would immedietally exist at the other end. It would be like programming with nondestructable bits. You can't just get more, you can't copy them, because they have to exactly match instantly.
A better example that transporters is Stargate wormholes. The matter is reconstructed in a field where the two halfs are never "Physics-ly" disconnected.
Does this not seem like cheating to anyone else? So they observed "action at a distance," and "spooky entanglement", and have observed the transmission of qubits from one light wave to another, but they did it all with a connecting fiber-optic cable! This makes it far less fascinating for me. It's not how Star Trek did things, and it's not the "spooky" phenomena I studied in college.
We learned the "jelly bean" analogy, that says if you had two quantum jellybeans, both simultaneously red and green, and gave one to your friend, and put one in your pocket and boarded a plane for some far-away destination, that upon landing at your new destination, if you put your hand in your pocket and pulled out your quantum jelly-bean, and observed that it was red, your friends's jellybean back at home would unquestionably and could only unequivocally be green. That's how we learned about entanglement. The existance of a connecting fiber in this case just seems too much like electromagnetic transmission, which quantum entanglement is not.

The only things known to go faster than ordinary light is monarchy, according to the philosopher Ly Tin Weedle. He reasoned like this: you can't have more than one king, and tradition demands that there is no gap between kings, so when a king dies the succession must therefore pass to the heir instantaneously. Presumably, he said, there must be some elementary particles -- kingons, or possibly queons -- that do this job, but of course succession sometimes fails if, in mid-flight, they strike an anti-particle, or republicon. His ambitious plans to use his discovery to send messages, involving the careful torturing of a small king in order to modulate the signal, were never fully expanded because, at that point, the bar closed.

On the other hand, I came across a paper which proves quantum key distribution safe against a "collective" attack which allows "quantum memory". I've had trouble understanding how a collective attack works: "each qubit is attached to a separate probe, unentangled to any other probe. The measurement is delayed until after all the classical data is obtained." This paper went way over my head. Maybe someone out in /. land can help with an intuitive explanation because I think the significance of this paper and the safe use of repeaters in quantum key distribution are related.
There are trillions of CELLS in your body. Don't even start on the subatomic particles!
I want to counter that with two points:
According to Quantum theory, no particles or physical entities have an identity other than the collection of their properties. This means that two particles of the same type and with the same properties are completely indistinguishable. This means that a human being destroyed, but replicated exactly somewhere else, will have the exact same properties aside for position, in other words - moved. If you're worried that changing your position is a problem, you're already dead :)
Many human cells are constantly dying and get replaced. Not many of the cells in the human body existed when the human was born. This means that your existing body/cells have been destroyed and recreated already - you simply didn't know.

I study at the University of Montreal where Gilles Brassard works, and I think in a class he talked about that specific article by one of his student. I don't have time to read it all, but here is what I remember:
When sending the quantum key, a spy can 'intercept' it, thus disturbing the key. So, Alice and Bob must find a way to detect those errors. They proved a way that accurately gives the % of error, thus knowing if someone disturbed the quantum information or not, and what % of information the spies has on the key, thus, making it a TOTALLY SAFE encryption method, as you accurately know if it worked or not. If it didn't, exchange another key, until the % is at a safe level. Even if the spy has 5% of the information, it's not enough to get anything useful out of the partial keys he has. To get the % of error, Alice and Bob compare a proportional portion of their keys. If there was no spies, it will be nearly 100% exact. If a spy eavesdropped, it will be disturbed a lot. They just found a fast, small, secure and mathematically proven way of comparing parts of the key, giving an accurate % of error and knowing if the key was disturbed or not.
If you do NOT check, the spy could intercept the key Alice sent to Bob, it would be disturbed, then Bob would think he has the correct key, then Alice send a message to Bob with the key, and the spy can read it, but Bob cannot. A VERY smart spy would, when he intercepted the key, create ANOTHER key, send it to Bob. Then, when he interecepted the message, he reencode it with the key he sent to Bob, and Bob would get the message correctly, thinking it wasn't intercepted. The paper proves that you can know if the Spy attempted this or not, making quantum encryption TOTALLY secure.
Ok, the above wasn't 100% clear:
Stupid spy:
------------------
A send quantum key X to B.
E intercept X, thus X is now Y.(qubit was distured)
B receives key Y.
A send encrypted message MX to B.
E intercepts MX. Decode it with X.
B receives MX, but cannot decode it with Y. He know someone intercepted the message, but it's too late. A and B stops exchanging info.
Clever spy:
------------------
A send quantum key X to B.
E intercept X, thus X is now Y.
E create quantum key Z and send it to B.
B receives key Z.
A send encrypted message MX to B.
E intercepts MX. Decode it with X.
E send encrypted message MZ to B.
B receives MZ. Decode it with Z.
Now, B thinks no one intercepted the message and key, so A and B continues exchanging info, and the spy E gets ALL the information.
This paper mathematically proved it's possible to know if Eve intercepted the key and send a fake one to Bob. Alice and Bob just have to compare a subportion of their key to know if there was a spy or not.
Hope this helped =) As fo the exact info in the paper... I couldn't explain it to you, it's not my field of expertise.
My error: this is the intercept/send attack I described above. This paper talks about a Collective Attack, and proved quantum encryption is secure against this one.
Sorry. Anyway, the same applies, it's a mathematical proof against another kind of attack. Just replace my example above with a collective attack example.
Sorry again, should have read it more carefully.
So what will happen if you leave something in the same place that the cloned atoms are reassembled in?
Wouldn't there always be something there, even if it was just air, in which case what happens to the atoms that existed in the space before? Do they have to be destroyed in order to make space, or are they displaced / merged?

Since these guys didn't use jellybeans but photons, they used a fiber instead of an airplane.
The spooky thing is not that if one bean is read, the other one is green. The spooky thing is that the information about the color travels faster than the spead of light (as a matter of fact, the transfer is instantaneous) which is why Albert found it spooky (mostly because it violates the principles of special relativity. But, then again, God DOES roll dice over his creation).
Ethics is what you say you do. Morals is what you actually do.
Finally I will be on time for school and work!! I wonder if the excuse the teleportation gizmo ate my homework will work?
The crux is, as you point out, the destruction of "the original copy" in the teleportation process. The implicit point in your argument is that the death of one of the copies matters. My question to that point is: To whom? Me-before-the-teleportation doesn't care - I will live on in the copy. The teleported copy is alive, so it doesn't matter to it. "The original copy" is "dead", and didn't mind before it happened.
The crux of the problem is really the SPEED of destruction. IIRC, over the course of seven years or so our bodies flush out and replace every cell in the body. That means that essentially we are composed of entirely different matter than we were seven years ago. Because the process is gradual and slow, we don't consider this to be a personal death and resurrection, we consider ourselves to be the same person we were seven, ten, or twenty years ago, though materially we are not.
Or put another way, if we had perfect organ transplanting technology and could replace bits of ourselves as they wore out, when would we stop being us? After the first new knee-joint? Most would say no. After the first brain graft to replace that failing visual cortex? How about after the 79th brain graft, which replaces the last of the old, decaying material?
Why should replacing this process, whether it be a natural one through the course of eating and shedding old cells or an artificial one through gradual organ replacement and grafts, with an instantaneous one be any different? Surely the mere compression of time doesn't fundamentally alter what is happening.
So we are left with two choices. ONE: we do die over the course of 7 years, and we are not the same people we were 7 years ago, we are merely self-deluded copies, or TWO: we are the same people, in which case the length of time is irrelevant, and a teleported person will be as much the same person they were before, whether or not the atoms that comprise them are the same ones (teleported) or new ones with a quantum signature imposed.
As to which belief one subscribes to, that is more of a religious or philosophical discussion, but whatever belief one chooses, one must apply it consistently to the natural replacement of ourselves, and any forthcoming organ transplant technologies, as much as one would to a hypothetical teleportatioin technology, and accept the implications of said belief.
Personally, I believe I am the same person I was 10 years ago (modulo gradual personality changes), and I would have no problem teleporting myself around the universe at lightspeed if such facilities were available to me. And if I am deluding myself, I'm not deluding myself any more than all of us already are every time we look back on the myth of our own past, so either way it is a wash.

I have an article at www.changhai.org on this topic (but written in Chinese unfortunately), whoever knows Chinese is welcomed to take a look.
I'm scared by teleportation.. I mean, teleporters murder people! Ok, Ok.. there aren't "teleporters" yet, but the way the ones in Star Trek work, disassembling your molecular structure, transmitting it or information about it to another location to be reassembled, thats death! Once you are disassembled you're never coming back!
..Not that I think people will overlook this fact when we have computers powerful enough to copy structures as complicated as a person.. Right?
The thing that is reassembled on the other side is just a copy of you with the last memory being disasembled, but appearing just fine in another place. It'll report back that the transportation was fine-- but you-- you'll be gone forever.
Mabye your soul will magically appear wherever your atoms are reconstructed or something... but the current technology they are working on is complete destruction, and then on the other side they use information about the destructed item to reconstruct it or make it appear as if it had been teleported, but its just a copy.
Noone will know if teleporting kills you or not because the only person who will know you have died will be yourself.
...unfortunately no one can be told what The Mat^H^H^HGoatse is...they must experience it for themselves...

This isn't a transporter story, this is a story about secure communications.
If you can transmit messages with entangled photons over an optical network, you can prevent anyone from "tapping" the line and observing your communication without you knowing. If someone fucks with one of the entangled photons, the other party will know.
You don't get it, this is not a copy of you, because you can not exist in two places in the same time, the instant it creates the new you it destroys the old you, there are never two "you" lol. And lets not get into does the soul transfer, if the chemicals in your brain transfer as they were then it will be you in a different location. Read Feuerbach, he kind of explains this idea, but not in respect to quantum physics, that is kind of after his time.
Read the article and look for a word starting with E and ending with T. and you'll understand why the number of particles won't matter in the end.
There's a rule in QM called "no cloning" which means you cannot make an exact copy of a quantum state without destroying that state. In other words, the Heisenberg uncertainty principle prevents you from duplicating a photon precisely. It does not stop you from teleporting that photon to a new location, thereby destroying the "original" photon.
This is done through a dual process. Part of the photon state is transmitted "classically," by measuring the photon and sending the information along a wire. The other part of the photon state is not measured, but "travels" to the new location via entanglement. The two pieces of information are put back together at the other side to recreate the photon. The process of making the classical measurement is what destroys the original photon. This destruction is unavoidable -- you can't end up with an identical copy of the photon, while still keeping the first photon.
Star Trek transporters could be a theoretical possiblity. But replicators cannot exist, because that would involve exact cloning of quantum states, which is impossible.
The important thing about this "teleportation" process to remember is: if you stick your hand into the region between the transmitter and reciever you will still get a hole burned in it by the perfectly ordinary beam of energetic, physical photons that is "teleporting" the information.
--Tom
Blasphemy is a human right. Blasphemophobia kills.
Employing a facet of quantum mechanics that Albert Einstein called "spooky action at a distance," scientists have taken particles of light, destroyed them and then resurrected copies more than a mile away.
Previous experiments in so-called quantum teleportation moved particles of light about a yard. The findings could aid the sending of unbreakable coded messages, which is limited to a few tens of miles.
The new experiment used longer wavelengths of light than earlier ones, letting the scientists copy the light through standard glass fiber found in fiber optic cables.
So what they did is destroy light, use light to transfer the "destroyed" light a mile away and "ressurrect" that light? That doesn't sound like teleportation to me. Its like using a laser beam to send a laser beam.

The teleportation of humans, objects and anything else is already possible and has been for thousands of years, but not with the aid of technological gadgets. The ability to create something out of nothing has been spoken about in religion since it's very conception and up to modern times.
Now before you scoff at the rest of the post thinking it is religious crap please consider the following scientific aphorisms:
1) There can only be one truth/one set of laws that govern the Universe. A simplistic example, gravity does not go both up and down and/or sideways, when you drop an object it always falls down. Over the last many centuries our scientists have proved over and over again that things in our physical universe behave according to a set of laws. Laws which even to this day science is discovering, which means we do not as of yet know or understand all of these laws. Therefore one can conclude that the very scientific community we praise and cheer for thinking they have all the answers - that very same community admits their ignorance. Every single day they claim to be discovering this or that. If you are at the discovering stage, then you can not possibly know everything.
2) If you read both ancient religious texts from several different religions (Christian, Buddhism, Hinduism, to name but a small few), all of them contain accounts of so called "miracles". What is a miracle? Is it really something that defies the natural laws of the Universe? No, that's hogwash. You can not claim the Universe is has 1 set of laws and in the same breath claim those laws can be somehow put aside and something takes place which defies those laws. That is just absolutely ridiculous - if we've learned anything from science it is exactly THAT! What is more likely as I've stated is that we don't know how all the laws work yet and when we see or hear of something which seems to defy the few laws we do currently know, we tend to say it is lies, or magic, or miracles or anything but something NORMAL. However; let's wind the clock back a few centuries and let's pretend we could teleport/travel back in time and bring with us some gadgets with us, say a video camera. We walk into the most advanced city on Earth at that time, say the Roman empire for example, and we tape Julius Caesar giving a speech.. then we walk a few miles away and show somebody who was not able to be at the speech presentation and we hit the play button. To the ignorant watching the movie playback on the LCD screen this is nothing short of a miracle, a magical act, how can after all Caesar and his entire palace fit inside this little box? And how can you possibly make him give the same speech exactly the same time after time???? I think you get my point. Those that have performed great feats in the past were not doing something beyond what is physically possible. A video camera that works in 2002 will work just as well in the year 1000 B.C. The laws of the Universe have not evolved over 3000 years - they are the same. Eternal and Immutable!
Miracles are given that name, IMO by those who do not understand how a specific feat was conceived. How did Christ turn water into wine? Or resurrect, or cure people with touch? How do Indian Yogi's or ZEN Masters perform acts of levitation or how are they able to accelerate the growth of plants by a factor of 20-100 times, making them grow right before your very eyes? How have so many Christian saints and Hindu Yogis performed acts of Bi-location (being in 2 places physically at the same time, witnessed being there and having conversations by different people at different locations at the same time?) These are just truly very few examples of the so called acts we name miracles and they have not all been performed by a single person, or claimed by a single religion. In fact at the core of every major religion you will find such miracles and claims of the so called super-natural, more correctly assigned the name of the occult mysteries (occult meaning hidden - do not confuse this world with some of the crazy cults going around). But the reality is not that it is super-natural... the reality is that it is natural, the average person just does not understand how such an act is performed. And this may sound like a surprise to you but believe me intellectual understanding will NEVER allow you to mimic such miraculous acts. The very same people
At any rate here, my point is, man can only accomplish what he is capable of imagining. If he can not imagine it, he can not create it.
But let's get back on topic, so how can teleportation be accomplished? Well, let's take a look at a simpler version of teleportation - clairvoyance. What is clairvoyance as most people understand it? It is the reading of thoughts, in particular images from the past or future and somehow having access to them in the present. This is a very common so called unexplained miracle performed today, however it is not called a miracle as much by most people because it has become far more common place and therefore a little bit more acceptable and considered closer to normal, yet not quite there because even the people who perform such feats can not explain in scientific or any other intelligible words how this is accomplished, at least not to the satisfaction of a scientist wanting to replicate the feat.
The fact that not Jesus, nor any Yogi, Zen Master, Christian Saint, or any high ranking Buddhist master are considered to be extremely high intellects possessing at the tip of their tongues the answers to all scientific questions serves to us as proof that it is not through scientific intelligence that teleportation can be accomplished today. It is therefore an act feasible today not by scientists possessing great intellect, but by their counterparts - the true spiritual man!
My friends, I could go on, and on and on... My point is science may one day be able to explain in intelligible language how teleportation of a human being can be accomplished, but I guarantee you it will not be within our life times and whenever it does one day become possible - if by scientists - it shall require very fancy highly complex and expensive machines. If you wish to teleport within your life time, your best bet are to not only study, but in particularly practice the occult sciences - i.e. Alchemy (the founding science of Chemistry initiated by Paracelsus - a science which combined chemistry and spirituality and philosophy in one great art, but the 2 more important parts of it have now been thrown out by those who chose not to see beyond what their eyes show them in the physical), Astrology (the founding science of Astronomy - Astrology combined the science of Astronomy with the spiritual and philosophical, but again modern-ignorant man has stripped out 2/3rds of that and chose to look at only what he could see. If you chose to ignore 2/3rds of reality, then do not expect to be able to understand the whole of the Universal laws! If modern scientists would learn this, we'd be centuries ahead in every aspect of evolution than we are today).

That being said, I say to you,what makes you, you, what exact part of your body is not allowed to be destroyed, to keep you you. Your brain cells die and new ones grow, your still you, people get heart transplants and I would say they are still themselves. Kidneys, skin, blood, platelettes, all kinds of things you can get at the hospital and still definitely be you. So what's the difference here. You and your friends, may not exactly be the think tank for the new millenium.
from what i have heard/read is the process of making a copy of something, destroying the original and sending the copy to the destination for recreation. if a human is teleported and is exactly the same as the original does the copy have the same soul?
in late breaking news the vatican has denounced teleportation as heresy.
I know you are psychotic, but please make an effort.
I think that putting all the emphasis on creating Start-Trek-like transporters misses the point. Imagine the kind of computers one could create using information-teleportation! This would give the whole notion of distributed comuting a whole new and fascinating twist. Using info-teleportation, computers could span the solar-system and be capable of gods-only knows kinds of computations. And think consider the algorithms that could run on such a computer.
stop being idiots. The two "you"s never ever exist in the same time frame. They can't meet, and both can not be kept if you believe in the laws of quantum theory. The whole idea is that the original is instantaneously destroyed as the new one is created. Why is this so hard to grasp?
"His team teleported qubits carried by photons--particles of light--of 0.05 inch (1.3mm) wavelength in one laboratory onto photons of 0.06 inch (1.55mm) wavelength in another laboratory 180 feet (55 meters) away along 1.2 miles (2 kilometers) of fiber optic wire."
So they "teleported" light over fiber optic wire. Uhmmmm right. Check. Now, I may not have a complete mastery of all that phancy physics stuph, but I was pretty sure this was the entire premise of fiber optics. Ya know .. light, distance, little glassish wire things, some lasers..
If you need me, I'll be over in the corner scratching my head.
That's not hard... I teleported this over a STandard phone line just a few minutes ago.
Yes. This brand new technology is acheived by using a photo transistor to detect photons and then creates a copy of the photons at a different location using a special new device called a Light Emitting Diode.
Is that this technology whould have more immediate effect on computing. This is an important step towards quantum computing. Why does the media focus on the sensationalized possible outcome (beaming people) and not the less glitzy, but HUGH impact of what this means to computing. This would revolutionize computing the way the transistor did.

A lot of people don't realise it, but "same" actually means something specific and is (scientifically, at least) not some woolly playground approximation. If Disk A is the same as Disk B (or whatever we are comparing), then Disk A IS Disk B.
A copy of something is just that, a copy, and may well be similar if your copy is good enough!

Well then the transporter can still be used for turning people into piles of goop.
ok .. I've thought about this for quite a while now and here's my take on it..
.. basically "star trek transporter, even replicator.. " replicator because as I understand it the food etc. that it produces is food that's already been scanned in.. anyway .. what if someone were to really invent that here in our world.. what would happen..
.. but it would be fought all the way .. could you imagine the great evils of the world.. (mpaa & riaa)!!! they would flip.. now not only could someone copy the content but actually the physical medium.. it would put an end to virtually every business in the world.. any company that produces something would be put out of business.. it would bring about the end to the economy as we know it .. I just think if something like this was actually invented .. the person and the invention would disappear rather quickly .. .. If I had a replicator at home I'd never have to buy another product again .. once it was scanned in..

you can move a whole electron with a single photon, and the conversion happens all the time. The energy of anilhiation shows up on gamma spectrometers, letting you know that mass to energy conversion is ongoing. Think I'm silly? Check out a whole buch of antimater. While moving electrons one puny light photon at a time might not work, more energetic photons may.

No sig, sorry.
I think there are almost impossible problems faced when transporting a specific object from one place to another. But in spite of that, quantum teleportation is a fantastic concept that hold much potential.
Beyond the communication possibilites, consider the transfer of energy. Could not a solar power station satellite in low SOLAR orbit beam back clean energy back to earth, thus, offering an unlimited supply of energy for us to use.
This talk of teleportation reminds me of Timeline. Its totally fictional but pretty interesting.
Spoilers....
This company stumbles onto time travel through experiments in teleportation. They attempt to send some drones through a teleportation device and some do not come through on the receiving end. They discover the drone was sent to another dimension. They then strap a camera to one of them and find out its been sent to another time(by aiming the camera towards the sky and checking out the star positions.) the story unfolds as an adventure where someone wanders to far from a time travel device and his friends go back to rescue him.
They are making a movie for this also and it comes out later this spring. Hopefully it will stay pretty close to the book.
Although most cells in the continuously die and are replaced, brain cells (and parts of the spinal cord) are "stuck" in a state prior to cell division, and do not replicate (well, certain types do under certain conditions, but they are a an extreme minority). So, even though your body is being continually replaced, the brain cells of an 80 year old are the same cells he/she had when born (so take care of your brain!). It is possible in the coming years that we'll be able to induce brain cells to divide and grow, allowing things like the "brain grafts", but I would argue that "you" are defined mainly by the specific interconnections of your brain, and more specifically the interconnections in certain parts of the brain (most peoples visual cortices behave in similar ways, while other parts clearly differ and give rise to your unique personality). To define yourself as not being "you" because part of your brain has changed is oversimplified, while a person's personality is the sum of all their parts, and changing any part does effect the whole, its not so much that you stop being who you are and start being someone else but rather that who you are changes to a greater degree than the way who you are changes every day.

How many times do you have to teleport before you become Kevin Bacon?
Has anyone measured it? Wouldn't it just shoot relativity to hell if quantem teleportation transferred information instantaneously?
For instance, I could measure exactly how fast we were moving and in what direction by measuring our time skew by synchronizing to a quantum state to measure the ammount of time it takes for a photon to travel so far. Basically, I would have an independant, third party perspective of time. You might just be able to measure the time skew by carrying a clock from point A to B, then point A recieves information from point B, and they both record the time. Either the clock traveling from point A to B was traveling faster, slower, or the same as the person from A (depends on weather the Earth is moving toward A, B, or neither). This means you could measure the discrepancy, and calculate if relativity is true, thereby proving or disproving the theory once and for all. (Though it would seriously be undermined in a lot of ways, you could prove part of it being true.) Either that, or we can patch the theory some more to make it work in another way it doesn't seem to. Einstein knew about these situations, a good study of this may help lead a little closer to a unified theory?
The only problem I could see is that you wouldn't know what you were sending, but how could quantum computers be useful if you couldn't set at least some value?

I wouldn't worry about it for a while - at least not until we get fusion reactors or something. Remember nuclear bombs? They take a small chunk of matter and turn it into a *VERY HUGE* release of energy. So, all you have to do is be able to create *that much energy* first, then find a way to stuff it back into and create matter (fyi - they have been able to do this in high-energy particle accelleration experiments - IIRC, some of the very short lived elements in the periodic table are created this way - but it takes a huge amount of energy, and you get very little out of it - at least currently)...
Reason is the Path to God - Anon
He imagined a system, described in his book Mind Children, called the Moravec Transfer, which is a form of mind uploading.
Now, I realize this isn't the same as what you are worried about here with teleportation - but the ideas behind the Moravec Transfer really causes one to think about what is MIND and the "I" of an individual - where does it begin, and where does it end. I think the way it is spelled out and discussed in the above link on the Singularity makes the case clear that it *is* possible (not with today's tech, of course) to transfer the mind to a computer, and there would be no difference in the experience - you wouldn't "die" with the method.
Interesting ideas, at the very least...

As you stated; this is not an outline for "three to beam up, Mr. LaForge" (Can't help it... I'm a TNG fan myself). But what does interest me is what bearing teleportation may have on quantum computers (accepting that both ideas have quite a distance to travel (sorry) before finally coming to fruition).

I can see the marketing department now. "10 Terrahertz thanks to transporter technology! It also doubles as a home furnace when paired with your 8942 PAL heatsink!"
Everyone's always worried about teleportation because of this concept of a 'copy' of the original person. Here's a little thought game that might change your mind.
If your hand got severed in a severe accident and they could reconnect it, but with wires, to the rest of your body, would you still be 'you'?
Now lengthen those wires to a mile away. You can still control your hand, are you still 'you'?
Now replace those wires with wireless, instantaneous 'action at a distance' connections, allowing you to move your hand from a distance with the power of your own mind. Are you still you?
Now think of this barrier of separation slowly moving down the length of your arm, where the vanishing arm is replaced instantly at the other end near your hand. You can see, move and think the entire time and even feel your arm and move it as the process continues.
As long as your thought processes are the ones moving the matter on both ends of the teleportation device, as long as your brain can function in two physcial halves because those halves are effectively connected and whole, there's no copy, there's only *you*. Don't discount the concept because one particular manifestation of it doesn't do what you want.
So all Captain Kirk needs to do is snake down a fiberoptic cable from the Enterprise to the surface of Rigel 7.
On another note, if you can send the signal over fiberoptic, instead of an "analog" transmission they will eventaully be able to encode it to a real digital signal; at that point, its just data and can be copied ad infinitum (or ad nauseum, depending on who is being copied...)
Manipulate the moderator system! Mod someone as "overrated" today.
The point of Schrodinger's Cat is that this kind of peculiar superposition of states cannot be confined to elementary particles that cannot be directly observed; it is possible to envision ways in which a superposition of a macroscopic object--even a living being--could occur. Recently, a method has been described for forcing a small mirror into a superposition of states, getting very close to a Schrodinger's Cat scenario.
the difference is quite possibly the poly-exclusion principle. I have only casual knowledge in the topic Indeed. It's the Pauli exclusion principle, named after Wolfgang Pauli. It does prohibit fermions from existing in the same quantum state, though, as you describe. However, the previous poster is also correct in stating that there are bosons which do not carry a fundamental force, and most bosons are actually quite massive. The key characteristic of a boson is integer spin- fermions possess half-integer spin. There are certain situations in which normally fermionic matter becomes bosonic matter, which is no doubt what the above poster was referring to with the Rb-80 example. Perhaps the best known examples of this sort of transition are Cooper pairs in superconductors. Below a critical temperature, crystal lattice vibrations (phonons) in type I superconductive materials induce electrons, which normally repel each other and normally follow the PEP, to pair up in weak, loose arrangements called Cooper pairs. Essentially, two half integer particles (electrons) form one integer spin particle (Cooper pair), which makes it a boson. Similarly, certain atomic nuclei with particular numbers and arrangements of neutrons and protons can act as bosons. This has long been known with simple atoms- this is what makes helium-4 superfluid at 2.17K, and has recently been demonstrated in much larger nuclei.

Certain cells are NOT replaced regularly in our bodies, most importantly the central nervous system cells.
/. article a while ago about how every time we "remember" a memory, it's actually re-written in our cells? Sort of like a DRAM refresh process. So you get some new frontal-cortex cells grown, somehow walk through your memories, thus getting them resaved into the new cells, before you weed out the old ones.
The nerve that runs from a motor neuron in your brain down to a muscle in your lower leg is ONE cell, and that cell doesn't regenerate if it dies.
This is why spinal cord injuries are such bad news, and why stem cell research (cells that DO grow) is so neat.
So when you're 80 years old, some of your most important cells are also 80 years old! I think this will be the most limiting factor in exending human life span -- we'll figure out how to reset telomeres to cause infinite regeneration of cells, so your skin, muscles, bones will all stay 20 years old forever. But those pesky CNS cells... aren't used to dying and being replaced.
But maybe they WILL be able to convince CNS cells to die, and get new ones to grow in their place. Conceivably, every 40 years you'd need a CNS cell flush, along with some rehabilitation to train in the new cells to function properly.

Or put another way, if we had perfect organ transplanting technology and could replace bits of ourselves as they wore out, when would we stop being us? After the first new knee-joint? Most would say no.

Speed is not the problem. Is there more to us than quanta is the question and the problem.
What if you could build a quantum duplicate without destroying the original. Which one would be the real you?
If the entire sum of our being is composed of our physical components as opposed to stored in our physical components, then there is no difference.
Either way, it's not speed that's the problem, it's a question of identity.

The fact that you are your same self 7 years later I beleive is because of the speed. Life revolves around cycles, which *is* time. You change that time frame, you change the life (let me put it this way: if you made the day 48 hours, how many plants would survive?).
Further, teleportation (unless absolutely perfect and instant) must have some form of "time freeze" in it. The only time you can define yourself as a "collection of atoms" is when you take a "snapshot" of yourself (ie: take time out of the equation). However, this snapshot does not say anything about, for example, motion. If I'm in the middle of a thought and get transported, will I finish that thought off? That means that the electrons around my brain must "remember" their projected motion and they all must "continue" at the same time. And unless the teleporter can "freeze" you until you are completely built (or if the teleporter is "perfect"), you'll either die or you're no longer the same person.
This does leave open "dead" object teleportation though.
Dan ...
Information wants to be free.
Information wants to be valued.
It's not just a question of time, it's also a question of degree. What this argument really hinges around, I think, is the idea of a soul. Does a person have qualities that are not described by the physical elements of their bodies? If no, teleportation is fine and dandy, reconstructing the atomic particles of a particular person at a distance will create the same person. But if a person does have a soul, this changes the equation. The general view of a soul is that its sort of "hooked" to the body during life, and upon death it is released to be destroyed, reborn, taken up to heaven, whatever. When you have organ transplants, only one thing is being "destroyed" at a time. Take out the heart, replace it, take out the lungs, replace them. But with teleportation, the whole body is destroyed, and then a bodily physically identical is reconstructed. When the body a soul inhabits is totally broken down, does it do what it does when the body dies, or does it hang around for a bit to see if the body's gonna be reconstructed somewhere else?
Just because you're paranoid doesn't mean there isn't an invisible demon about to eat your face
I think I had a quantum aneurysm reading these articles. I think I understand entanglement but I fail to understand how it is being applied in this specific circumstance at all.
I followed the course of Gilles Brassard on Quantum Computing at University of Montreal. He is one of the inventor of the Teleportation theory (with bennett, crepeau, peres...).
What he could tell about that is what is said in media is not exactly true. In that theory (and the experiment) they teleport quantum state of a particle. Teleportation is useful in quantum cryptography (take a look at the paper from Nicolas Gisin "Quantum Cryptography") and many other aspect of quantum computing... But it has no relation with teleporting an object (like in star trek)
Try to find the paper "Quantum Cryptography" published in 2002 by Nicolas Gisin from Ecole Polytechnique Federal de Lausanne . It s the state of the art for quantum cryptography.
