In this research area, we conduct research for “cleverly using” quantum as opposed to the research for “creating” quantum computer hardware by the integration of quantum bits and the control technology. “Cleverly using” here means to create a technology that works under restrictions provided by quantum mechanics and limitations in implementation, and enables large-scale quantum computation under a realistic environment.

　As the contents of the research, our targets include a wide range of themes other than the development of hardware, such as the quantum architecture and quantum software to realize the fault-tolerant quantum computer, the quantum algorithm to solve problems more efficiently than that in the conventional method, the high-level quantum information and communication technology that integrates the quantum sensor and the quantum computer, the information processing system that integrates the quantum technology and the classic IT technology, and the application to solve the social problems by using the quantum algorithm.

　Through the integration and collaboration across various academic disciplines, we aim to advance the research and development of innovative information processing methods and to create a technological foundation for realizing the quantum computing that can be deployed in the society.
