University of Tokyo researchers have demonstrated an electrically-controllable valley current device that may pave the way to ultra-low-power valleytronics devices.
Pursuing foundational technology leading to quantum computers
A quantum computer is scheduled to make its first appearance in Japan before the end of fiscal year 2019. The D-Wave quantum computer will be installed in the research center formed by Tokyo Tech and Tohoku University. To date, Tokyo Tech researchers have been accessing a machine installed outside Japan via the cloud. But now progress is being made to join Tokyo Tech s basic research with Tohoku University s applied research, and also cooperate with industry to develop a global research hub. In the field of quantum computers, filled with brilliant, global-scale advances in R&D, Associate Professor Tetsuo Kodera is working to develop foundational technologies using semiconductor silicon. We asked Kodera and two of his students to tell us about the current state of quantum computing and the outlook for its evolution.
