Quantum computers can achieve extremely fast computations for certain problems using quantum properties. Due to these factors, research and development in the field of quantum computers have been vigorously pursued. It is crucial to develop a quantum computer that operates accurately and, concurrently, create applications compatible with quantum computing. Quantum computer simulators are tools that represent the behavior of a quantum computer on classical computers, and they are highly conducive to the development of quantum applications that can run on actual quantum computers. On the other hand, quantum computer simulators run on classical computers, which are extremely slow compared to quantum computers. Therefore, it is desirable for the development of quantum applications to be able to fully utilize the computational resources on a classical computer and run at high speed. In this paper, we analyze the performance of the Qiskit Aer simulator, the Qulacs simulator, and mpiQulacs on various types of single servers. We then compare the performance of these quantum computer simulators across different computer environments.
