The researchers used this experimental setup in light by destroying one quantum teleportation and he recreate remotely in another location. (Science/AAAS)Researchers at the Australia and the Japan managed téléporté of the wave of light, potentially revolutionized computing and quantum communication packets.
The team, led by researchers at the University of Tokyo, said that it was the first teleportation, or transfer, of a particular complex set of quantum information from one point to another.
According to them, it will make possible transmission at high speed, high fidelity of large quantities of information, such as encryption keys of quantum, via communications networks.
The research appeared Friday in the journal Science.
Elanor Huntington, Professor at the school of engineering and Information technology at the University of New South Wales, Australia, explained that the teleportation - transfer of quantum information from one location to another using normal, "classical" communications - is a fundamental quantum communication technique.
"It is based on having two things", she said.
"One is normal internet optical fiber or copper even cables and the other is a resource shared between the sender and the receiver, which can have been shared at any time in the past: we call this tangle.".
Huntington says the idea of quantum teleportation is a decade, but it was difficult to put into practice.
"There used to be two ways of teleportation and both have their limits," said.
"One was fast enough, but had limited success probability." The other way to do so has been very slow, but had a very good chance of working. ?
"What we have accomplished is managed to get it quickly and of good quality," she said.
They did by teleporting light wave packets in a "Schr?dinger cat ' State."
In the famous 1930s Schr?dinger thought experiment, a cat would be placed in a sealed box with a device containing radioactive material. A Geiger counter has been included to measure radiation if at a given time, an atom rotten. Should this happen, the Geiger counter would result in the rejection of cyanide gas, which would kill the cat.
The idea was that it was impossible to know whether or not the cat was living or dead without opening the box and observation, and that until this is happened, there were two realities. This became known as an overlay.
Schr?dinger is supposed to have designed the experiment to ridicule the new theories of quantum physics; Since then, physicists have found many examples of layering in the quantum world.
"What was funky on the idea of Schrodinger was that you could take a normal macroscopic object, which we believe all about us and understand quite well, and you can place it in a quantum superposition - and it's a little weird""stated Huntington."
"Now any kind of system where do so you is known as a Schr?dinger cat."
"In our case that we have therefore take a macroscopic beam of light and put it in a quantum superposition, which is extremely fragile, and teleported to a place to another."
"One of the ways encode us digital information is by its phase" Huntington says, "so what we've done is created a wave packet which is at the same time and a zero phase."
"Overlay is exactly behind the power of things like quantum computers". You enable a parallel processing, because at the same time, it is one and zero. "The point is that we have managed to teleport it from a to b without one and zero is confused,", she said.
Huntington said be able to demonstrate this will enable researchers to move to the next step in quantum computing.
"[Being able to transfer data as packets] is something necessary to build a quantum computer, appropriate or quantum communication device," she said.
