Scientists "Teleport" Quantum Information One Meter
the4thdimension writes "While we may not be beaming up to the Enterprise anytime soon, a team of scientists from the University of Maryland and the University of Michigan have managed to teleport information between two atoms up to a meter apart. Until this point, only very tiny distances were able to be traveled. However, using a complicated system of photons, ions, lasers, and electromagnetics, scientists have managed to 'teleport' information contained on one atom to another atom that is in a separate sealed container. This can lead to a wide range of developments in computing and communications."

I think we discussed this a week ago.
My work here is dung.
I hope at least one scientist in that lab had the balls to shout "Beam me up Scotty!!!" during the experiment

I watched a BBC documentary 'Visions of the Future' online a couple of days ago, and a team in Vienna had already teleported information between photons years ago. See here, about 50 minutes in. (I recommend watching all three programmes, it's an interesting documentary). The professor in the video states that the record stands at 600 metres. I'm no physicist, so could someone explain what is so different about what has been achieved in the article? Is the difference between teleporting information between photons and atoms so distinct?
Mother, do you think they'll like this sig?
I've been "teleporting" information several yards ever since I got a wireless router.

I posted it in the origial thread and it appears in the dupe thread.
BTW I am patenting 'Teleposting' as I like to call it.
Do not try to read the dupe, thats impossible. Instead, only try to realize the truth
What truth?
There is no dupe
...is for the whole week in between the experiment simultaneously existed as both a success and a failure.
Didn't they read the c'eth commandment ?
Thou shalt not teleport information from 1 atom to another atom at a speed greater than thy Lord hath deemed forbidden[1] lest thou wishes to kill thy grandfather before thou art born - and create earth engulfing black holes in the process[2].

[1] Ok.. I didn't read TA.. so what ?
[2] That's last sentence is not in the original text - consider this creative license.
Yeah, it seems like every so often, there's another story in the media that "teleportation has been achieved," or "we can make things invisible," or "scientists have made light go faster than light." They go on to explain all the great things we could do if we could teleport things, go faster than light, and make things invisible.
Then, down near the bottom somewhere, they finally explain that no, we're not talking about real teleportation, but rather quantum entanglement that can't really be used for communication. We're not talking about real faster-than-light travel, but making a light wave that sort of looks like it's going faster than light but isn't. We're talking about something that might be useful for stealth airplanes, making them invisible to radar, and not real invisibility. Stuff like that.
And then they tag some throw-away line at the end like, "But who knows, maybe we'll be able to teleport to the moon next year!"
I hate journalists.
While I agree with you, it is one way of cathing the public's eye. Journalists want to make headlines, when they can't, they make up headlines remotely tangential to whatever material they've got.
My beef is with the Slashdot editors; when I started reading Slashdot, it was because the editors chose interesting stories. They still do, this is interesting, but they choose to present this particular mainstream article as the only link in their ingress as documentation and background information. I find that sad.
Are you a grammar Nazi? I'm trying to improve my English; please correct my errors!
I'm wondering, if this process uses entanglement how does that work with the No Communication Theorem? I thought that entanglement could not actually transfer useful information.
