Abstract— Although a quantum computer is future of computing, its practical implementation is still far off. Programming a quantum computer is also difficult. Thus, the quantum computer simulator is a way to learn and use a quantum computer. QCL is one of the quantum computer simulators. It can simulate a quantum environment and execute quantum computer programs. However, the quantum computer simulator has limit storage due to the data structure that simulates quantum bits. It takes a long time to simulate quantum bits. This work proposes an accelerator of quantum simulator using hardware circuits implemented in Field Programmable Gate Array technology.
