Physicists Discover How To Teleport Energy
MikeChino writes "A physicist at Tohoku University in Japan has figured out how to teleport energy from one point in the universe to another. The technique is based upon prior research that shows it's possible to teleport information from one location to another, and involves making a measurement on each [of] an entangled pair of particles. The measurement on the first particle injects quantum energy into the system, and then by carefully choosing the measurement to do so on the second particle, it is possible to extract the original energy. Heady stuff, but essentially it means that you can inject energy at one point in the universe and extract it from somewhere else without changing the energy of the system as a whole."
How would an experiment like this be interpreted using the consistent histories theory?
For a classic entanglement "teleportation" scenario where a measurement on one particle could cause information to be "teleported" to the state of the other particle, I think the consistent histories interpretation of quantum mechanics says that the second particle was always in the same state until it was measured, and that no information was exchanged.

On another note, is there a way to test if this is correct?
Are there direct practical applications for this, if it is correct?
I've wanted a BET Transmitter ever since I saw GI Joe: The Movie.
How long before something like this makes it's way into communications? Granted it's no 'beam me up Scotty', but it's getting pretty damn close, at least from an energy perspective. Is this instantaneous across a distance?
Best. Physics quote. Ever.
"He gives the example of a string of entangled ions oscillating back and forth in an electric field trap, a bit like Newton's balls."
If you can inject enough energy into the process this could in theory be the replacement for batteries. This is provided you could make a giant transmitter that sends to the receiving devices. (Or possibly battery replacement modules?)
;-)
This is provided the technology isn't only "ten years away" or so.
"Bah!" - Dogbert
If the two entangled particles only appear in our holographic 3D space to be diverging, while on the actual 2D horizon they are still coherent, any form of 'spooky action at a distance' makes perfect sense. If you inject energy into one of the particles, it makes sense that this should be transferable to the other.
If I recall, in Mass Effect 2 they used entangled particles for instantaneous long-distance transmission across the galaxy!
Exactly how do I get the 'second' particle to where I want the information to be retrieved?
Great minds think alike; fools seldom differ.
mobile devices of the future come with entangled "battery" pairs: plug one in at home an voila! no more recharging...
Information. Well I mean besides the states of the 2 entangled particles. (You look at one, it's state is set and therefore the entangled particle gets it state set.)
Did you know 80 to 90% of the moderators on slashdot wouldn't recognize a troll even if one dragged them under a bridge.

So we can put the solar panels in a "close" solar orbit (or even earth orbit) and entangle/detangle the power into our grid?

Fuck systemd. Fuck Redhat. Fuck Soylent, too. Wait, scratch the last one.
Speaking as a Physicist, it seems the title should be " A physicist has posted a preprint in which he claims that "energy can be teleported"
(as opposed to beiing transmitted)." and someone has praised it in a blog post.
The astract says
"Protocols of quantum energy teleportation (QET), while retaining causality and local energy conservation, enable the transportation of energy from a subsystem of a many-body quantum system to a distant subsystem by local operations and classical communication through ground-state entanglement. We prove two energy-entanglement inequalities for a minimal QET model. These relations help us to gain a profound understanding of entanglement itself as a physical resource by relating entanglement to energy as an evident physical resource. "
note "classical communication" (i.e. a telephone call from one place to another) to tell the recipient what to do to extract the energy is needed.
Note that an arxiv post is an assertion by an author, prior to any refereeing. The are only minimal "fences" at arxiv.org to keep out the "Einstein was wrong, I am right" nuts.
This tech, if ever made viable on a larger scale would be the perfect way to transfer solar energy to the ground, much more efficient than the currently proposed lasers.

It's Not That Kind Of Teleportation
And the first comment on TFA is, of course, someone saying how this can be used for FTL communication.
I've been doing that for years. I shove a pizza in my mouth and it teleports to my ass!
If Google really cared they would fix Android Chrome to reflow text, instead of discriminating
if this really works and can be very precise then you can teleport energy to a moving spacecraft making serious space travel a reality. no longer would you need to carry ANY fuel.
Energy teleportation could mean no more need for any kind of fuel.
Heck... even if the send/receive station is to huge to be portable it would still eliminate any other form of powerplant.
Just chuck some solar sails on huge platforms up into space and point them towards the sun.
For the extra credit, get them there by pumping energy collected on Earth into their receiving station and use ion engines to set them up at the most desired position.
Then, do what they do on Star Trek all the time - reverse the polarity.
Pump the energy they collect back to Earth using the very same station that got them there.

Although I've already read about this concept, I'm glad to see that there is progress being made. It's been said that we can make the most efficient computer in the universe by utilizing every process inside a black hole, and it's been theorized that we can send in quantum entangled atoms, and leave the other half out of the black hole to keep the result of the computation available. This means we can utilize the power a black hole can deliver without having to enter it at all. The atoms will keep the same spin as their entangled partners and therefore we can computations and energy back out.
as a free lunch.
Haven't read the papers yet.
But actually the argument that quantum teleportation doesn't break relativity theory was that no information/mass/energy is moved at speeds beyond lightspeed. Like if you use it to transmit information, you need a 2nd channel that goes at lightspeed max. like to tell the target station how to do the measurement, or not ?
So mmmh, teleporting energy ... how can it work then ? Need to read more about it...
Generation Ship!
People both here and on the linked blog article seem to be thinking that this "teleportation" talk is all about sending things from one place to another faster than light. That's not the big deal; it's already well-established that that cannot be done, at least not via quantum entanglement.
The breakthrough the article is talking about is moving energy from one place to another "instantly" by means of performing the right pair of measurements on both end; but the communication between ends about what measurements to make still happens at light speed or less.
For example, say I have a bunch of particles here on Earth and my colleagues on Mars have another bunch of particles entangled with mine. Mars is at the moment ten light-minutes away from each. On my end, I perform a measurement on (i.e. I interact with) my particles in a way which raises their energy from X joules to Y joules; I then send a radio transmission (with said transmission using less than Y-X joules) to my colleagues on Mars giving them instructions for what measurements to make on their end, i.e. I transmit information, in normal ways, at the speed of light or less.
Ten minutes later, my colleagues on Mars get my message, perform the measurement, and BAM, the energy of their particles jumps up to Y joules. The most efficient classical alternative for transmitting that (Y-X) joules of energy would be to beam a signal of said energy between the two points, but that requires a clear line of sight between them, or some set of relays capable of carrying that signal, each of which adds inefficiency to the transmission. An even less efficient, even more classical method would be to take whatever the energy is stored in here on Earth and physically move it to its destination, which is both much slower and much less energy-efficient.
With this method, my colleagues could be buried deep underground in a sealed lab with no way of getting anything in or out except for a limited range of radio signals carried by equipment incapable of carrying high-power signals... and still I can "beam" them arbitrary amounts of energy straight into their lab just beaming energy into some particles in my lab and then telling them over the radio what to do in their lab to receive it.

If you can transport power then you can avoid the mass issues with interstellar travel. An array of solar collectors orbiting the Sun would power ship indefinitely so long as panels were replaced. Mass would still have to be "sucked up" along the way to use for propulsion unless some form of gravity drive was developed. Mass for power was always the biggest thing holding back interstellar travel.
If people figure out how to teleport troops or nuclear weapons into my basement it will be VERY BAD! There have been a few sci-fi stories examining the impact of teleportation which I can't seem to remember. Perhaps some literate slashdot members will enlighten us? I would discuss this in greater detail, but there is a Homeland Security truck in front of my house and there is someone at the door...
Sorry, but gray text on gray background is making my eyes bleed.
Please, someone come up with an automotive explanation, Quick!
The problem with quotes on the internet, is that nobody bothers to check their veracity. -- Abraham Lincoln
Also, how much energy does it take to do the correct measurement to receive the transmitted energy?
Depending on how much energy can be transferred in this method, would it be possible to mass a large amount of entangled pairs and send them into the Sun (or a solar array in space) that could then transmit that energy back to the other pair located somewhere on Earth?
Limitless energy with no loss to transmission... Sweet deal...
BTW, which do you think will come first? The civilian or military use (if the military isn't already using it in some fashion...)
It seems weird because in the quantum teleportation protocol you cannot transfer information faster than light. Furthermore, you can teleport a qubit in the excited state (therefore teleport energy) but the transfered energy is already "delocalized" in the entangled particles shared by the sender and the receiver and the protocol only allows you to localize it at the receiver's end. So you still have to transport your entangled particle, which cannot be done faster than light. The formalism the guy uses in his article is unhelpfully heavy and I doubt his conclusions are good. I say you can indeed teleport energy (think of it as teleporting a chain of excited states) but you cannot do it faster than light. There is also a problem with carrying around a system with a lot of entangled energy, it will have a small gravity field and it will decohere very fast, rendering it useless.
Now we can finally start strip mining the sun!

Sounds like another one of Maxwell's Demons. "If something were smart enough to assess the properties of a local particle..."
So you can instantly teleport energy to Alpha Centauri, but it would take over 4 years for your phone call to reach them, telling them about it?
And add another 8 years if they say "WHAT? Can't hear you."
I am anarch of all I survey.
note "classical communication" (i.e. a telephone call from one place to another) to tell the recipient what to do to extract the energy is needed.
Yeah, but that doesn't make it useless. For example, imagine your television came with an entangled remote control, and it communciates the necessary information "classically" with one of any available low-power wireless transmission methods. The remote can then use whatever power it needs through its "entanglement battery". There you go, a remote control that never needs new batteries.
I'm just extrapolating, assuming that you actually can "teleport" useful amounts of energy wirelessly through this process, so I have no idea whether it would actually work, but the need to communicate information through classical channels does not mean the whole concept is worthless.
Using time sequencing you can now transfer binary data. Energy at this time code (i) no energy at this time code (0).
So you can now have real time control of distant space craft and rovers.
Undetectable Steganography? Yep, there's an app fo
Its easy, all you need is to already know what information it is going to send!
Those of you who are married surely have large amounts of data on this FTL communication device!
James P. Hogan wrote a sci-fi novel about this back in the 70's, I think. The Genesis Machine. The technology was weaponized fairly quickly -- why use a warhead to deliver phenomenal amounts of energy when you can just deliver the energy?

You know, oblivion keeps looking better every day.
Editors, I love ya, but if anyone on earth really did discover "how to teleport" anything, I'm pretty sure I'd be seeing it scroll by on the CNN news ticker right now. It wouldn't be the first time /. has scooped the media complex, but so far its been 2 hours since the story was posted, and I don't see any breaking news on Channel 6. Seriously, enough with the sensationalist headlines. Call me when you have my flying car or jet pack ready.

If this becomes practical, will we not even need to create fusion? Can't we just teleport energy from the sun?
Imagine for a moment, that you build a dyson sphere around a small ( lets say, asteroid sized event horizon) black hole, which has a single aperature through which you can feed it. Near this aperature, is an energy collection system (lets be imaginative here, afterall-- this is a thought experiment.) which extracts the obscene energy released by the matter flow as it gets constricted from gravitational influences of the black hole, and begins to emit high intensity X-rays, gamma rays, black body radiation, and the like.
Since the black hole is naturally deleterious to any habitable/habitated area, simply because of the chaos its gravity well would cause, you need a way to transmit this obscene amount of energy to the population center, which could be several tens, or even hundreds of light years away.
If you use this energy entanglement transfer mechanism, you can transfer this absurd amount of energy to the population center at the speed of light, with a very tiny fraction of the losses incured by trying to beam it there, and without any of the line-of-sight issues.
EG, a single power plant on the planet's surface would have access to the full power of the black hole power plant. Moreover, the energy produced by the black hole plant, and transported to the planet in this way, could maintain the entanglement states at both ends.
Such a solution would safely provide nearly unlimited power to said hypothetical civilization, and do so for billions of years. (assuming that the power plants are maintained.)
Forget ZPMs-- You could drive planet building machinery with this approach.
I wonder why nobody mentioned this, but wouldn't "teleportation"-based communication be impossible to eavesdrop on?
If that's the case, it would have applications even across distances where classical communication is still "instantaneous".
Bad news for cryptographers though...
They want their energy back. :-)

Could all mass and energy in the universe have come from random fluctuations nearby a big black hole? I don't understand why the generation of pairs of particles does not produce no net effect on the black hole (so, no evaporation) if matter and antimatter pairs created by vacuum fluctuation quantum events have one or the other fall into the black hole at the same rate? If there was a preference for antimatter from the created pair to go into black holes, that might explain the existence of the material universe. :-) And all the anti-matter to balance the matter created from the vacuum is safely tucked away inside one or more big black holes. (A tiny asymmetry of anti-matter being having a teeny bit more gravity than the same amount of matter might explain that, or if some type of anti-particle attracted anti-particles more than particles, that might also explain that.)
A 21st century issue: the irony of technologies of abundance in the hands of those still thinking in terms of scarcity.
How about a few thousand solar satellites in orbit around the sun, transmitting energy directly to power stations on earth where the energy gets redistributed?
How about no more batteries?
Driving cars that get their energy straight from the sun?
Cellphones that do not just get their energy through an entangled pair, but also their 'net connection?
Or why not just dump one of those entangled particles into the sun? Or, if we're feeling particularly paranoid, into a neighboring star?
From the abstract of the article:
Protocols of quantum energy teleportation (QET), while retaining causality and local energy conservation, enable the transportation of energy from a subsystem of a many-body quantum system to a distant subsystem by local operations and classical communication through ground-state entanglement.
There's an important line in there: while retaining [...] local energy conservation. What lies at the heart of the proposal is that the measurement devices add or remove energy from the system that they are measuring. The energy is in no way removed from one location and given to another, spatially distant, location. What happens, is that a measurement device at one location gains energy from the quantum system and, based on the outcome of that measurement, the measurement device at the second location can be configured to lose energy into the quantum system at that location.
The thing to take away is that no energy is lost or gained at either location. Instead, the measurement devices at each location gain or lose energy to compensate changes in the energy of the system. This proposal is in no way a method to teleport energy in the intuitive sense; the total energy of the quantum system and measurement device at each end is conserved. The notion that measuring a system changes the energy of the state is very fundamental in quantum mechanics and is well understood. Honestly, there's nothing particularly new about it and the paper doesn't appear to be written to be submitted to a major journal.
This reinforces my opinion that people need to stop submitting papers they find on arXiv, especially single-author papers.
So if this is the future...where's my jet pack?

This sounds very similar to the Icarus Array in Peter Watts' novel, Blindsight. The premise (of the drive, I'll try to keep out any story spoilers) as I understand it is that entangled communications require a traditional EM signal to operate, but that they can transmit far more information than that signal alone could. It has nothing to do with FTL communications, simply "piggybacking" a whole lot of extra data using an otherwise normal communication signal. In the novel, unless I misread it, the same principal is used to transmit energy from a solar station very close to the sun to a ship way out in the oort cloud. Apply the same principal to energy and you can use a dinky little communications laser to set up a "quantum channel" (wrong term, I'm sure) that can carry an enormous amount of power. Sending that amount of power as a high intensity beam of EM radiation would not only need a huge collector at the recieving end but would be incredibly dangerous to anything between the source and the sink, like another ship.
With this method, my colleagues could be buried deep underground in a sealed lab with no way of getting anything in or out except for a limited range of radio signals carried by equipment incapable of carrying high-power signals... and still I can "beam" them arbitrary amounts of energy straight into their lab just beaming energy into some particles in my lab and then telling them over the radio what to do in their lab to receive it.
OK, so let's say that you send them (via radio, or penguin-post, a flung shoebox, whatever) a series of expected time sequences that you will be transmitting data, minutes, hours, days, or weeks in advance. And then, at the expected times, you either send X joules of information, or not, indicating a binary state. (or perhaps you send anywhere from 1-10 joules of energy, indicating 10 possible information states)
In a way, you aren't sending any information faster than the speed of light, because the real information is being sent via penguin-post. But you could still instantly notify the other side that Obama won his 2nd election without having to wait for classical physics transmits that data, correct?
I have no problem with your religion until you decide it's reason to deprive others of the truth.
You can't "transmit" the energy unless you also use classical transmission methods to send over the information on how to extract the energy at the other end. So you're left with the same issues there are for quantum communication - whatever you send "instantly" is no good until you can send a classical signal to extract some value out of it on the other side. Well, if you're still having to send things the old fashioned way anyhow, then what advantage are you even gaining from using the quantum method at all?
How long until I can say "beam me up Scotty?"
"He who teleports Emma Watson to his bed chambers wins"
So the idea here is apparently that the energy itself can be transmitted instantly, but you can't actually transmit information this way. Just energy
... which would immediately violate the principle of the conservation of energy.
The problem here is that energy == matter (via e=mc^2) and the system of matter/energy together in space-time yields information. Beckenstein shows that the total information in a volume of space is described by the area of the volume which encloses it. See "Bekenstein Bound" http://en.wikipedia.org/wiki/Bekenstein_bound/
So in order for this new theory to work, the energy that is instantly transfered to another point in space-time must not be useful until we know what we can do with it through the classical channel. Otherwise you violate the conservation of energy.
Consider for example a mass at height in a gravitational field. To hold the mass stationary at height without any means of support other than using some of the mass itself for the creation of thrust, you would neccessarily run out of mass eventually (time). But if this theory were true, you'd have a loophole where you could take the energy expended for thrust and send it instantaneously back to the point in space above the mass where it could thusly be re-utilized. You would then have your first anti-gravity machine, which can't exist. A mass at height can be used to create energy in free-fall, and which is only equal to the potential difference in height. See http://hyperphysics.phy-astr.gsu.edu/HBASE/gpot.html
Btw, this is why theoretical wormholes can only exist along gravitationally equal field vectors. If a wormhole were to connect two different locations in space that don't exist with the same gravitational potential, you could generate an almost infinite amount of energy. Consider two ends of a wormhole, one end at 1000 meters height above the earth, the other at the ground. Throw a very large mass in at the ground hole. The mass then appears at 1000 meters, and starts falling. You could then make energy from it indefinitely. (What's that video game? Portal?) I would assume, in such a scenario, that the two ends of the wormhole would neccessarily begin to edge closer and closer to each other until they "evaporate" from existance altogether. This might be similar to black hole evaporation.
My question is, what actually is the total amount of energy required to actually hold any object at height, indefinitely, in a gravitational field?

And now we only have to figure out how to transform matter into energy and vice-versa in a non-destructive way and we can start building Galaxy Class starships.
they may have transmitted it as energy, but matter is just energy in standing waves. so we just need a (very) fancy wave generator, insane processing power, an ultra fast scanner at the sending end, and of course a disintegration beam to vaporize you once your copy is made; then it's star trek here we come.

Wait, it's posted in the arXiv *and* there's a blog post? Slashdot threshold exceeded.
The requirement for a telephone call might be negated somewhat by using a rules based approach to the measurement process.
Incidentally, this could also enable QE to transmit very basic binary information based on the excitation states. (then again, I could be full of shit, and probably am! lol!)
An initial telephone call establishes the connection, and after that, both experimenters adhere to a measurement framework:
Physicist A measures his particle and sees that it has spin up. He calls is colleague and tells him to measure spin. Colleague reports that his particle is spin down. At this point, both physicist A and physicist B adhere to a testing protocol; The protocol dictates what Physicist A will do next, without having to tell physicist B, since Physicist B has the protocol documentation as well. Thus, Physicist B already knows what Physicist A will try next with their pair of entangled particles. (For instance, induce an excitation of a XXX eV on his particle.) Physicist B then automatically knows to look for a purturbation in his particle's energy state, and by how much.
Once physicist B measures and records the energy fluctuation, he in turn manipulates the particle in a pre-defined manner, which physicist A is now looking for in his entangled partner, after having done his own manipulation earlier.
The two physicists do not communicate with each other in any way after the initial phone call to establish the initial relationship. They continue to manipulate the particle according to the protocol, then begin monitoring afterward, after a pre-set period of time.
After several rounds of this protocol based experimentation, they transmit the results of their observations and the timestamps of when the observations were made, and when they manipulated their particles, and then compare the results.
This experiment is repeated many times to determine what the fidelity of the entanglement channel is.
After this point, the protocol is expanded to handle a kind of "Token Ring" based approach. Physicist A calls Physicist B, they evaluate what orientation each others particles are, then the new protocol dictates that A should "Send a message" by manipulating his particle in a predefined manner. Since this is an experiment, B already knows what the message will be, and how it will be encoded. He then monitors his particle for purturbations that correspond with the protocol and content of the message transmission.
He then waits the agreed time before sending his own message, which A already knows as well. (think, ICMP PING)
After vollying their messages over the particle pair, they call each other, and fax each other their observation data.
By analyzing the fidelity of these transmissions, a better protocol with error control can be derived.
This is where it gets interesting. A calls B, they determine orientation, then A sends a previously undisclosed message, using the agreed and previously exchanged error correcting protocol. B monitors the random fluctuations of his particle, until he detects that the random fluctuations correspond to the patterns predicted by the protocol, records the fluctuations, then decodes the message. He calls A, and verifies the message.
This is repeated several times.
The next experiment is A calling B, establishing orientation, and sending a private message containing instructions on how B is to manipulate his particle using the excitation protocol. B intercepts the message, decodes it, then performs the manipulation. A monitors his particle for the entangled result on his end. A and B call each other, and compare notes.
The final human experiment, has A and B establish orientation, then has A send yet another set of instructions to B. B decodes the message, follows them according to protocol, then sends his own set of instructions. This gets volleyed several times back and forth with unique instructions being sent each time.
A and B compare notes, and determine the reliability of the channel
I've seen a lot of posts with very good math talking about how it's not realistic to move data or energy across a field. But I'd submit that whenever these study's come up they always move said data or energy along something outside the inside part of the nuclear field that someone is dealing with.
Really, I know what I'm doing...Ohhhh, look at the shiny buttons!
There is nothing transmitted between "entangled" particles, nor are any relevant bits of information passed between them in any method that comes close to the definition of "teleportation", or even "transportation". The quantum mechanics behind "entagled" particles should be described like this:
1.) You have 2 Rubick's Cubes.
2.) You "entagle" them by making the faces of each Cube exactly identical to the other.
3.) You separate them physically into different geological locations.
4.) You "measure" Cube A by turning one of its sides.
5.) You call a handler at Cube B using a "common channel" (phone).
6.) Cube B is "measured" by having its identical face turned exactly replicating Step 4, per the instructions received by step 5.
7.) Repeat steps 4 through 6 until your heart is content.
8.) Bring the Cubes together, and marvel that their faces are still identical to each other.
I think the principle problem with "quantum teleportation" is that any measurement on one Cube which is not duplicated exactly on the other, breaks the entanglement of the particles. They are only "entangled" in the sense that their states have been synchronized. There may be avenues of recovering the synchronization using permutations of "measurements", but then I haven't read much about what occurs during an error or fault in measurement, so this is all just my best guess.
Thank you for reading One Man's Opinion. No participation necessary. Offer void where deemed by law or PATRIOT Act.
It would be great to be able to beam your molecules across space and then reassemble them. The only problem is that you have to trust your co-worker to operate the transporter. These are the same people who won't add paper to the photocopier or make a new pot of coffee after taking the last drop. I don't think they'll be double-checking the transporter coordinates. They'll be accidentally beaming people into walls, pets, and furniture. People will spend all their time apologizing for having inanimate objects protruding from parts of their bodies.

Put him in the games...
If you can teleport E, then given m=E/c^2, then you can teleport 'M'. It's a slow build up from 1 bit of 'E', to many bits of E, but the referred to article also mentions the ability to transfer small bits of matter in the not too distant future being a possibility -- from there, it's only a matter of scale and time (perhaps money and energy) before such technology could feasibly transport humans. Theoretically, that is...
But today's theory and sci-fi could easily be tomorrow's science fact.

Sorry to burst your bubble but you can't transmit information faster than light.
Period.
How do you know that?
We only know the laws of physics, well - as little as we DO know about it.
Maybe there's something faster than light - that we don't know yet?
What this world is coming to - is for you and me to decide.
From what I gather from the summary, you have to first measure the first particle, then measure the second in a way determined from the first particle. That means that firstly, you have to expend energy to separate the entangled particles, and secondly, you have to expend energy to transfer the information of the first measurement to the second measurement. So in effect, you have to expend a net of more energy through conventional means, i.e. the receiver has to expend more energy than it gains through the energy teleportation. That makes this technology for whatever possible future energy-reciever applications you've got there null'd.
this is a BOMB...
This would be the best use for such a technology. Now we just have to wait to see if it gets done...
Having large solar panels on a space station transmitting energy to the ground would be very clean and somehow reasonable (everybody should realise that most of the energy emitted by the sun is wasted outside the orbital plane).

1.) You have 2 Rubick's Cubes.
2.) You "entagle" them by making the faces of each Cube exactly identical to the other.
3.) You separate them physically into different geological locations.
4.) You "measure" Cube A by turning one of its sides.
5.) You call a handler at Cube B using a "common channel" (phone).
6.) Cube B is "measured" by having its identical face turned exactly replicating Step 4, per the instructions received by step 5.
7.) Repeat steps 4 through 6 until your heart is content.
8.) Bring the Cubes together, and marvel that their faces are still identical to each other.
Except that isn't how it works.
Here's a neat page which goes to some lengths to explain why people are excited and mystified by this particular feature of reality.
It is a high school science level presentation, but frankly, that's my level and with something as peculiar as Quantum Entanglement, it helps to go through the steps as a refresher. If you want to skip ahead, then the goods can be found on this page.

is it just me or proof by experiments is hard to come by these days ?
I just fill up my tank with entangled particles and the gas company will disentangle them as I drive along? That's neat!
No sig today...
Couldn't we remove the need to have a classical channel for communicating the method of extracting the energy by using some kind of 'protocol'? Maybe a time-based system or something? So that no matter where the particle is, the mechanism for extracting the energy can be identified in advance?
If this really works, then we can actually do FTL communication - vary the energy levels you are sending through and...
other commenters have already speculated on powering a spacecraft by such
teleportation of energy... how about going one further, could this leveraged
towards transmitting momentum?
instead of merely transmitting energy for the ship's propulsion to use, take a
derivitive of this as the propulsion itself... imagine using the earth, sun, or any
other sufficiently large mass with a convenient energy resource as the reaction
mass for a ship to remotely push against.
however, if the entanglement is destroyed upon extraction of energy, then the
spacecraft could still be required to carry a large supply of entangled particles...
perhaps using photons would mitigate the impact this requirement, subject to other
tradeoffs?
Yes, its all still slower than light, and requires a classical communication channel,
however, the efficient propulsion potentially achieved would still be revolutionary.
If, however, its true that this effect doesn't even so much as transfer energy as
sensationalised, then of course nevermind. Though i would point out the energy
appears to be described as conserved for the whole system, as opposed to the
each of the 2 remote subsystems some commenters seem to have taken it to mean.
IANAP, though, and my interpretation could just be naive wishful thinking; anyone
who knows better is encouraged to poke the appropriate holes through this notion.
If talking about state changes only, this seems like a potential candidate for a scientific variant of the D&D clone spell..

still no giant robots. For shame Japan, for shame.
can anyone say mass effect 2? quantum disentanglement.
Didn't Nicola Tesla do something similar?
