Successful quantum teleportation

A team of researchers from the University of Tokyo in Japan and the University of New South Wales in Australia, led by Noriyuki Lee, has succeeded in teleporting non-classical wave packets of light from one place to another. This, simply put, means that for the first time it has managed to send data from one site to another instantly, without using the "slow" classical photons are capable of exceeding the speed of light. According to the authors of the paper, the system could be used in the design of quantum computers faster and capable of delivering information securely and instantly.

For years, scientists looking for ways of making quantum teleportation provided by the laws of physics in a real device. The "small print" of quantum physics says that under certain conditions, it is possible to transfer information between two points instantly, without the limitations imposed by the speed of light. But one thing is that something is possible (or permitted by the laws governing the universe) and quite another to build an apparatus that becomes a reality. There have been several experiments, some surprising results, but it seems, have been researchers at the University of Tokyo in Japan along with the University of New South Wales in Australia, led by Noriyuki Lee, who have been successful in build what they call "a teleportation device bandwidth and zero dispersion."

The system could be used in the design of quantum computers faster. The system could be used in the design of quantum computers faster.

The results of this work have been published in the journal Science. Basically, what did these scientists was sent from point A to point B a number of quantum-level data expressed by photons. Obviously, the interesting thing about this is that these particles have been used in the same way that profit within an optical fiber, but quantum effects have been used with such strange names as "constraint", "photon subtraction" "entanglement" and "homodyne detection." The result has been a teleportation device capable of teleporting non-classical wave packets of light from one place to another making for the first time to transfer all the information without losing any fragments in the process. In this experiment, the points of departure and arrival (A and B) were relatively close, but the theory behind all this nonsense technological forecast is possible to do the same between any two points of the Universe.

"A teleportation device capable of sending non-classical wave packets of light from one place to another without losing any fragment."

Needless to say that an accomplishment like this, become a commercial device, change the way we communicate. The ability to instantly transfer data (or whatever it is, in a time equal to zero) implies that we may, for example, receive all our emails in a flash, download 1TB of data in the same time, or any else you can think of. But there are some more subtle implications. If this technology becomes part of microprocessors, for example, its processing speed would also increase dramatically, because the signals that travel through it could get from one end to another device in no time. According to the authors of this paper, the system used could be used to design quantum computers really amazing features.
