Hybrid Quantum Systems

Yoshiro Hirayama is Professor at the Department of Physics, Graduate School of Science, Tohoku University, Japan. He received his Ph.D. in Engineering from the University of Tokyo in 1983. He joined NTT Basic Research Laboratories the same year and served as Group Leader, Distinguished Technical Member and Executive Manager. In 2006, he took on his current position at Tohoku University. In the course of his work, he has led numerous research projects on semiconductor quantum transport, carrier interaction and quantum coherent systems, e.g. “Nuclear Spin Electronics” funded by ERATO-JST (2007-2015) and the Grant-in-Aid for Scientific Research on Innovative Area “Science of Hybrid Quantum Systems (2015-2019). He is also Fellow of the Institute of Physics (London) and the Japan Society of Applied Physics (JSAP). Koji Ishibashi is Chief Scientist at Advanced Device Laboratory, RIKEN, and Team Leader at the Quantum Effect Device Research Team, RIKEN Center for Emergent Matter Science (CEMS). He received his Doctor of Engineering degree from the Graduate School of Engineering Science, Osaka University in 1988. He switched to RIKEN in 1988 and served as Researcher in the Frontier Research Program and at the Semiconductor Laboratory. He took on his current positions at the Advanced Device Laboratory and the Quantum Effect Device Research Team in 2003 and 2013, respectively. At present, he also serves as Adjunct Professor at Chiba University, Tokyo University of Science and Tokyo Institute of Technology and as Visiting Professor at Universiti Teknologi Malaysia and Osaka University. Kae Nemoto is Professor at the Principles of Informatics Research Division, National Institute of Informatics. After serving as Researcher at Queen’s University in Australia and the University of Wales in England, she joined the National Institute of Informatics as Associate Professor in 2003 and was promoted to her current position in 2010. She is Fellow of the American Physical Society and the Institute of Physics. She was honoured with an HP Labs Innovation Research Award from Hewlett-Packard.
