Principal Investigator

Seigo Tarucha

Seigo Tarucha received the B. E. and M. S. degrees in applied physics from the University of Tokyo in 1976 and 1978, respectively. He joined NTT Basic Research Laboratories in 1978 and received the Ph. D degree in applied physics from the University of Tokyo in 1986. In 1998 he moved to the University of Tokyo as a professor in the Department of Physics and then to the Department of Applied Physics in 2005. Since April in 2013 he has been concurrently serving as a director of quantum functional system research group in Riken Center for Emergent Matter Science. He was a guest scientist in Max-Planck-Institute (Stuttgart) from Jul. 1986 to Nov. 1987 and in Delft University from Jul. to Oct. in 1995. He is currently working on quantum transport and correlation effects in semiconductor nanostructures and spin-based quantum computing with quantum dots. He was a coordinator of Global Center of Excellence program for Physics in Tokyo university from 2008 to 2013 and has been a co-PI of "Quantum information system", Funding Program for World-Leading Innovative R&D on Science and Technology since 2009.


Tomohiro Otsuka

Hi. This is Tomo in RIKEN CEMS. I'm interested in quantum transport in nanostructures and its applications to creating new exciting devices. I would like to enjoy new science with friends in and out of this center! I received the BS, MS and PhD degree in physics from University of Tokyo. I joined Tarucha group in the University of Tokyo and now this team.

Takashi Nakajima

I received the BS degree in physics and the Master of Arts and Science degree in basic science from the University of Tokyo in 2005 and 2007, respectively. I worked as an assistant professor in Prof. Susumu Komiyama's group in the Department of Basic Science in the University of Tokyo from 2008, and received the PhD degree in 2010. In 2012 I joined Prof. Seigo Tarucha's group in the Department of Applied Physics in the University of Tokyo. Since 2013 I have been a postdoctoral researcher in QFSRG, CEMS in RIKEN. My main research interest is in fundamental quantum mechanical phenomena in mesoscopic systems, e.g., entanglement, coherent transport, quantum dot, spin electronics, quantum Hall effect, and cavity-QED.

Kenta Takeda

I received the B. Eng. in physics and the M. Eng. degree in basic science from the University of Tokyo in 2010 and 2012 respectively. I joined the Tarucha group in 2009 as a bachelor student. My current research topic is the realization of spin qubit in Si/SiGe quantum dots. I am more generally interested in transport properties in mesoscpic systems.
