Creation of New Technology Aiming for the Realization of Quantum Information Processing Systems

Research Supervisor

Yoshihisa Yamamoto (Professor, Research Organization of Information and Systems / Professor, Stanford University)

Year Started



This research area targets research that aims to create new technology as the infrastructure for the development of systems for controlling quantum dynamical phenomena observed in the micro-world and implementing information processing of memory, computation operations, etc. Specifically, it targets technologies for basic devices based on quantum effects and the utilization of multiple quantum bits, quantum information transmission and relay technology involving optical, electron, atomic, nuclear and other systems. It also targets elemental research as the basis for those technologies, for example, empirical research including simulation relating to the control and observation of the quantum entanglement phenomenon. Specifically, this includes quantum computer technology using ion traps, cold atoms, electron or nuclear spin in semiconductors, Josephson junction elements, NMR, linear optical systems, etc., quantum relay technology using atom clusters or quantum teleportation, quantum encryption technology using single photons or entangled photons, etc.
