Eisuke Abe

Unit Leader, Superconducting Quantum Electronics Joint Research Unit


This unit develops quantum technologies based on superconducting quantum circuits at millikelvin temperatures, with particular emphasis on quantum computers on a scalable platform. Previously, the PI has also worked on spin-based quantum bits in various semiconductor systems, such as isotopically controlled silicon, optically active self-assembled quantum dots, and nitrogen-vacancy centers in diamond, and their applications to quantum computing, quantum communication, and quantum sensing.
