Research summary
Development of simulation technology for quantum computers for the "Fugaku" and other HPC system, to accelerate quantum information technologies.
Main research results
Development of quantum-computer simulator for massively-parallel HPC system using the state-vector method has been continuing. In 2007, 36 qubits simulation was achieved, 45 qubits in 2019, and 46 qubits now on the "Fugaku".
