Research and education activities

Monthly Workshop

Each member talks about his or her work in this workshop. It will be a great chance to hear comments and suggestions for your research.

Weekly Colloquium

One of us talks about a scientific paper, in which his or her research is involved. Each member usually has 2 talks in a year.

Weekly Journal Club

We study several textbooks written about our research topics [Optical Electronics (Yariv), Quantum Computation and Quantum Information (Nielsen and Chuang) etc.] Every week we have time to discuss the fundamentals of our research.

There are seminars of visiting researchers several times per year. We always encourage our graduate students to talk about their researches in the academic conferences (Annual Meeting of Japanes Physical Society or Japan Society of Applied Physics, for example).
