Abstract

Quantum computing realizes high-speed calculation with massive-parallel computing of quantum state transitions. The quantum computing emulator, however, must be able to manipulate exponentially increasing states as the problem scale increases. To reduce the number of quantum states to be manipulated in the emulator, we have focused on the quantum-state transitions in a quantum computer. In this paper, an emulator representing the state transitions with the location of a nonzero quantum state is proposed. As a result, the emulation of larger-scale quantum algorithms can be realized with a finite amount of hardware.
