Eisuke Abe
Unit Leader, Superconducting Quantum Electronics Joint Research Unit
Outline
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.
