Brief Biography

Eisuke Abe is currently a research associate professor at Keio University, Japan. He received his doctoral degree from Keio University under the supervision of Prof. Kohei M. Itoh. From April 2006 till December 2009, he was a research associate (assistant professor) in the group of Prof. Shingo Katsumoto at Institute for Solid State Physics, University of Tokyo, Japan. He then spent a year and a half at University of Oxford, UK, working primarily with Dr. Arzhang Ardavan and Dr. John Morton. In July 2011, he joined the group led by Prof. Yoshihisa Yamamoto of Stanford University, USA, and National Institute of Informatics, Japan. The group later moved to RIKEN Center for Emergent Matter Science, Japan, where he was a research scientist until March 2015. Throughout his carrier, his broad research interest has been in spins in semiconductor systems (isotopically controlled bulk silicon, electrostatically defined quantum dots, optically active self-assembled quantum dots, and more recently nitrogen-vacancy centers in diamond) and their applications to quantum information, quantum communication, and quantum sensing.
