Prof. Akira Furusawa and his group at The University of Tokyo, Prof. Jeremy O’Brien at University of Bristol, Dr. Alberto Politi at University of Southampton and NTT Device Technology Laboratories integrated the core circuits of quantum teleportation, which generate and detect quantum entanglement, into a photonic chip.
While there has been significant progress in current technology of information processing, its performance is said to be reaching the fundamental limit of classical physics. On the other hand, it has been predicted that principles of quantum mechanics enable us to realize ultimate large-capacity communication (quantum communication) and ultra-high-speed computers (quantum computers), overcoming the limit of current technologies.
