Explore and exploit the quantum world for information engineering and social technology

Ever since we were born, we have learned and adapted to the laws of our surroundings and the natural order. This has shaped our view of nature. However, in the microscopic world, we follow natural laws that we have never experienced in our lives. That is the quantum world. The practical application and spread of quantum computers that utilize the rules of that world is, in fact, rapidly approaching, and the development of quantum human resources who will play a key role in the quantum information society is an urgent issue. Our laboratory is conducting research on "quantum computers," which are computers based on a new principle that wisely utilizes the principles of quantum mechanics, from the basic to the applied level, and through this research we hope to contribute to the development of quantum human resources.
