ETH researchers cannot ”beam“ objects or humans of flesh and blood through space yet, a feat sometimes alluded to in science fiction movies. They managed, however, to teleport information from A to B – for the first time in an electronic circuit, similar to a computer chip. The ant depicted on top of the superconducting circuit illustrates the relative proportions of the macroscopic electrical circuits for the first time used for teleportation.

(Photo: Jonas Mlynek / ETH Zurich) (large view) 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, which is published in the current issue of the scientific journal Nature, the researchers were able to teleport information across a distance of about six millimetres, 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.
