Physicists successfully teleports information in electronic circuit for the first time

Washington, August 15 : Researchers have managed to teleport information from A to B, for the first time in an electronic circuit, similar to a computer chip.


Physicists at ETH Zurich have for the first time successfully teleported information in a so-called solid state system.

The researchers did it by using a device similar to a conventional computer chip. The essential difference to a usual computer chip is that the information is not stored and processed based on the laws of classical physics, but on those of quantum physics.

In a study, the researchers were able to teleport information across a distance of about six millimeters, from one corner of a chip to the opposite one. This was shown to be possible without transporting the physical object carrying the information itself from the sender's to the receiver's corner.

Andreas Wallraff, Professor at the Department of Physics and head of the study, said that quantum teleportation is comparable to beaming as shown in the science fiction series 'Star Trek'.

"The information does not travel from point A to point B. Instead, it appears at point B and disappears at point A, when read out at point B," the researcher said.

Wallraff said that this is interesting, because such circuits are an important element for the construction of future quantum computers.

Another advantage of the system of the ETH-scientists: It is extremely fast and much faster than most previous teleportation systems. In this system approximately 10,000 quantum bits can be teleported per second. A quantum bit is a unit of quantum information.

The study is published in the scientific journal Nature.
