Current Members (2025.04.01~)

Short Biography: received his PhD degree in Electrical Engineering from Osaka University, Japan in 1991. He worked as an Assistant Professor in Department of Material Science, Himeji Institute of Technology from 1991 to 2000. From April 2000, he joined the Department of Applied Physics, Hokkaido University as an Associate Professor. From April 2010, he leads the Ultrafast Quantum Optics Lab. as a Professor.
In 1996-1997, he developed the basic technology of "Polariton Imaging" as a Visiting Scientist under the Professor Keith A. Nelson at Massachusetts Institute of Technology, USA. In 2018-2022, he has been a joint appointment professor of Department of ElectroPhysics, National Yang Ming Chiao Tung University, Taiwan.
Current research topics of his group include the coherent control of an electron spin and nuclear spin ensemble in an individual quantum dot and the quantum memory using isotropic purified Er:YSO.

Short Biography: received her PhD degree in Applied Physics from Hokkaido University, Japan on March, 2011. She has investigated the interaction between an electron and nuclear spin ensemble in single semiconductor quantum dots in her doctoral course. After a postdoctoral fellow of Japan Society for the Promotion of Science (April, 2011-March, 2012), a research associate at Hokkaido University (April, 2012-May, 2012), and a Assistant Professor (June, 2012-March, 2023), she works currently together as an Associate Professor. She is tackling new challenges in electron-nuclear spin coupled system in semiconductor nanostructures. She has also started to study the optical properties of transition metal dicargogenides (TMDs).
