The goal of this research roadmap is to develop and build solid-state quantum bits, devices, and architectures for quantum logics or other relevant future technologies. Our major efforts include innovative device design, nanofabrication, and integration of conventional and emergent materials to resolve the major obstacles, or even to create new design principles, to achieving quantum computing and technology. The research team has so far achieved many pioneering advancements in semiconductor quantum electronics. For example, they developed the world’s first all-electric all-semiconductor spin transistor by employing quantum point contacts as the spin injector and detector.
