Publication number: 20240080185Abstract: A result confirmation unit (204) computes a state space probability that is a probability that a verification target device (300) has not correctly prepared a state space having a quantum state stored therein, a Pauli measurement probability that is a probability that the verification target device (300) has not correctly performed Pauli Z measurement and Pauli X measurement, and a magic state probability that is a probability that the verification target device (300) has not generated a magic state of CCZ. Then, using the state space probability, the Pauli measurement probability, and the magic state probability, the result confirmation unit (204) computes a degree of approximation between a quantum state and the magic state of CCZ at the verification target device (300) and measurement accuracies of the Pauli Z measurement and the Pauli X measurement on the quantum state at the verification target device (300).Type: ApplicationFiled: October 31, 2023Publication date: March 7, 2024Applicants: Mitsubishi Electric Corporation, NIPPON TELEGRAPH AND TELEPHONE CORPORATIONInventors: Akihiro MIZUTANI, Ryo HIROMASA, Yusuke AIKAWA, Yuki TAKEUCHI, Seiichiro TANI
