Prof. Akira Furusawa (Graduate School of Engineering) and his team, in collaboration with NTT and RIKEN, have succeeded in developing a squeezed optical fiber-coupled quantum light source, which is a key technology that will lead to the realization of a rack-size large-scale optical quantum computer. This is a stable and maintenance-free system using optical fibers and optical communication devices with excellent noise immunity, and is an achievement that can advance the development of actual optical quantum computers. This paper was published in Applied Physics Letters on December 22.
