Implementation of an Quantum Circuit Simulator Using Classical Bits

The quantum computer has attracted much attention since it can reduce running time of many tasks such as factorization and search compared to classical computers. However, the actual quantum computer is difficult to get access, and the classical computer has a problem of calculation time and computation cost grows exponentially with increasing the number of qubits. In this paper, we address an efficient quantum circuit simulator including quantum circuit emulation hardware and its software framework using classical bit. Also, the proposed quantum circuit simulator operates the same as the conventional quantum software framework and shows a fast operation speed.
