Hmmm, 'Teleportation' In An Electronic Circuit For The First Time

Physicists have successfully teleported information in a solid state system for the first time - they moved information from A to B for the first time in an electronic circuit, similar to a computer chip.

The essential difference between their method and the 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. 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.

"Usually, in telecommunication information is transmitted by electromagnetic pulses. In mobile communications, for example, microwave pulses are used, while in fiber connections it is optical pulses," explains Andreas Wallraff, Professor at the Department of Physics at ETH Zurich and head of the study.

In contrast, quantum teleportation does not transport the information carrier itself, but only the information. This is possible due to the quantum mechanical properties of the system, in particular the entanglement established between the sender and the receiver. For non-physicists, entanglement constitutes a "magic" link between the two parties which exploits the laws of quantum physics.
