Abstract
A result confirmation unit () computes a state space probability that is a probability that a verification target device () 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 () 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 () 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 () computes a degree of approximation between a quantum state and the magic state of CCZ at the verification target device () and measurement accuracies of the Pauli Z measurement and the Pauli X measurement on the quantum state at the verification target device ().
