  • Publication number: 20240080185
    Abstract: 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).

  • Publication number: 20220347732
    Abstract: A coil skid on which a hot-rolled coil 1 obtained by coiling a hot-rolled steel sheet is placed includes: at least two or more layers of a metal plate 11 and at least two or more layers of a heat insulating material 12 each stacked alternately, in which the metal plate 11 is in contact with the hot-rolled coil 1.
