We are conducting research on novel semiconductor quantum information devices that will support the information society in the future. Our current major research topics include the development of quantum interfaces linking light and spin to realize secure long-distance quantum communication networks and intermediate-range quantum links for large-scale integration of quantum computers, by utilizing the quantum nature of spin of a single electron in a quantum dot, a nano-scale size box of semiconductors. From semiconductor nano-device fabrication using state-of-the-art microfabrication techniques to the use of quantum transport measurements combined with advanced quantum state controls, we are studying the fundamentals of semiconductor spin quantum technology and its applications.
