Eh? Let me know when I can be beamed somewhere else, like New Hampshire.

interesting...LONDON, England (Reuters) -- Beaming people in Star Trek fashion is still in the realms of science fiction but physicists in Denmark have teleported information from light to matter bringing quantum communication and computing closer to reality.
Until now scientists have teleported similar objects such as light or single atoms over short distances from one spot to another in a split second.
But Professor Eugene Polzik and his team at the Niels Bohr Ins ute at Copenhagen University in Denmark have made a breakthrough by using both light and matter.
"It is one step further because for the first time it involves teleportation between light and matter, two different objects. One is the carrier of information and the other one is the storage medium," Polzik explained in an interview on Wednesday.
The experiment involved for the first time a macroscopic atomic object containing thousands of billions of atoms. They also teleported the information a distance of half a meter but believe it can be extended further.
"Teleportation between two single atoms had been done two years ago by two teams but this was done at a distance of a fraction of a millimeter," Polzik, of the Danish National Research Foundation Center for Quantum Optics, explained.
"Our method allows teleportation to be taken over longer distances because it involves light as the carrier of entanglement," he added.
Quantum entanglement involves entwining two or more particles without physical contact.
Although teleportation is associated with the science-fiction series Star Trek, no one is likely to be beamed anywhere soon.
But the achievement of Polzik's team, in collaboration with the theorist Ignacio Cirac of the Max Planck Ins ute for Quantum Optics in Garching, Germany, marks an advancement in the field of quantum information and computers, which could transmit and process information in a way that was impossible before.
"It is really about teleporting information from one site to another site. Quantum information is different from classical information in the sense that it cannot be measured. It has much higher information capacity and it cannot be eavesdropped on. The transmission of quantum information can be made unconditionally secure," said Polzik whose research is reported in the journal Nature.
Quantum computing requires manipulation of information contained in the quantum states, which include physical properties such as energy, motion and magnetic field, of the atoms.
"Creating entanglement is a very important step but there are two more steps at least to perform teleportation. We have succeeded in making all three steps -- that is entanglement, quantum measurement and quantum feedback," he added.

This has always been theoretically possible, it was only a matter of time. Quite frankly they should have done this years ago. We always knew that certain subatomic particles seem to have relationships that are seperated by space, they seem to know exactly what the other will do. This was unexplainable at the time i read about it, but if two different particles can react with each other in a what seems to be an impossible fashion, then teleportation is not too far fetched either.
The greatest thing is that we can possibly use it to go to other planets. Send machines to build us a sustainable home base, then zap us over there. It would rule.
^Holy . Its an alien.
In English Please?
there were experiments in the past that showed two particles seperated by space seemed to 'know' what the other was doing, by means of moving in completely opposite directions, like that
they had know way of explaining it
but it worked every time
I understood, I was just giving you for your above normal understanding (or knowledge) of physics.
Beam me up Scotty.
The way I see it, the new physics should be taught to kids from kindergarten.
Are you kidding!!!
Their heads would explode if you tried to teach them quantum nonlocality (BTW that is the phenomena that CBF described above... although I would be surprised If he could really explain its intricacies...)
Physics needs to be taught in a manner highly intertwined with its historical context.
Anyhow we are still trying to overcome the obstacles presented by the ever-hindering Heisenberg Uncertainty Principle... when we can -- I'm willing to bet a whole new world of physics will be unveiled.
there was a do entary about the early stages of this process on tv that ive seen, how they were tryin to teleport and ...
That was implied by my statement:

Be afraid.....be very afraid.
DRM, you are being so immature. Every one knows that you have to have weapons grade plutonium, a sports car, and be moving at 88 miles an hour to get the flux capacitor running in order to travel back in time.........geez.
This will open up a portal to another dimension.
Another dimension beyond that which is known to man. It is a dimension as vast as space and as timeless as infinity. It is the middle ground between light and shadow, between science and supers ion.
So theoretically I could transport my fist to Batman's face from my desk without having to move ?
I never said teach them quantum nonlocality but you can teach it in baby steps, quantum physics is the most exciting dimension of science out there.
And I dont know that much about quantum nonlocality but I have read of it. You would be surprised, eh? Well I was surprised when you told us Einstein was a proponent of Intelligent Design. So I guess you do know alot more about quantum physics than any of us.
For clarification I said Einstein believed in the existence of GOD as a supreme being and Creator -- although he did not believe in the Judeo/Christian definition of GOD. This of course being a statement taken from several Einstein biographies out there and one which should have no bearing on your possible gauging of my knowledge of physics.
Nevertheless --- physics is phun!!!!!
yeah I don't think the dude realizes how condescending he sounds sometimes. Then again he has a double PHD on god knows what, so...
My bad, he didn't say einstein believed in intelligent design. He said Einstein believed in creationism. Which is all the more surprising!
If stating facts is condescending well... I'm sorry. It doesn't seem like the problem is in the delivery but in the receiver's interpretation.
Besides, I don't know if you realize how many times CBF has tried to take my posts out of context for the benefit of his points. And if I have to deal with that habit of his in a manner that will prevent from wanting to repeat the offense, I will. Apparently, though, it isn't working - CBF is still waiting for a chance to topple my credibility. Whatever.... I could really care less.
BTW... I never said I had PHD's in anything. That's how rumors get started. I have multiple bachelors' degrees and a masters' degree in Bio-engineering... and as fate/destiny would have it.... I work at a refinery.
Don't shoot the messenger.
"It was, of course, a lie what you read about my religious convictions, a lie which is being systematically repeated. I do not believe in a personal God and I have never denied this but have expressed it clearly. If something is in me which can be called religious then it is the unbounded admiration for the structure of the world so far as our science can reveal it."
-Einstein, March 24, 1954
