We are making researches on Quantum Optics and Quantum Information Science at Department of Applied Physics, The University of Tokyo.
Program & Application
UTokyo-ANU Workshop on Quantum Control and Electronic Materials and Devices
March 25-26, 2020 at the University of Tokyo

Japan-Denmark seminar @Copenhagen (Nov.2019)

Furusawa Lab attended a seminar at Niels Bohr Institute in Copenhagen as a representative of Japan. It was held in the historical room which is seen in the framed photo. We believe that quantum mechanics was born in the room. Prof. Furusawa sits at Niels Bohr's desk.
