Research and Development of Quantum Computers Based on Superconductor and Semiconductor Devices

Abstract

Quantum computer is able to compute some of the hard problems which cannot be solved by conventional ones. Toward practical application, large-scale integration of qubits is necessary. Solid-state devices, such as superconductor and semiconductor qubit devices, are promising candidates to realize the large-scale integration. This paper reviews the current status of research and development of quantum computers based on superconductor and semiconductor devices.
