Research Field and Overview

Quantum information processing is an ideal information technology which suites low-energy dissipation and high information security. We aim at demonstrating the ability of solid-state quantum information processing with spins and topological phenomena. Our research targets are implementation of small to medium-scale quantum processing circuits with spins in silicon, development of control methods of quantum coherence and entanglement, and in addition development of control methods of topological particles providing new concepts of quantum information.
