RIKEN Center for Quantum Computing Quantum Computing Theory Research Team
Team Leader: Keisuke Fujii (Ph.D. (Eng.))
We focus on quantum software engineering science, which is necessary for the realization of quantum computers. We will develop basic technologies to exploit the performance of quantum computers on a scale that is now being realized or will be realized in the next few years, as well as applications of them to fundamental physics, quantum chemistry, and quantum machine learning, and we will work on quantum computer architectures, quantum error correction, and optimization of quantum circuits to realize large scale fault-tolerant quantum computers. We are also interested in interdisciplinary fields between quantum information science and fundamental physics, quantum chemistry, machine learning, and high-performance computing.
