Teleportation done on a microchip

The strange new world of quantum physics is moving closer. Physicists at the University of Queensland in Australia have achieved teleportation on a computer chip, transporting an atom from one location to another inside the chip.


The strange new world of quantum physics is moving closer. Physicists at the University of Queensland in Australia have achieved teleportation on a computer chip, transporting an atom from one location to another inside the chip.

The results were published in Nature magazine this month by Dr. Arkady Fedorov and Dr. Matthias Baur from the university’s ARC Centre of Excellence for Engineered Quantum Systems and the School of Mathematics and Physics.

According to a report in phys.org, Dr. Federov explained that the operation was possible through the laws of quantum mechanics: “the key resource of quantum teleportation was a special type of correlation, called entanglement, shared between a sender and a receiver.”

He said this was the first time the process of quantum teleportation had been used in a circuit to relay information and explained that the quantum information is stored in “quantum bits” that surprisingly can even be seen with “bare eyes.”

He said that in the future the technology could be used to quantum information over larger distances directly by microwave.

The technology is likely to be used in secure communications and for more efficient information processing.
