Abstract: An information processing apparatus determines a combination of a first data qubit and a second data qubit that further reduces the energy represented by an energy equation. The energy equation includes first to third energy terms. The first energy term is used to identify the first data qubit on which a Z error has occurred. The second energy term is used to identify the second data qubit on which an X error has occurred. The third energy term reduces the energy as the number of data qubits each being a third data qubit on which both a Z error and an X error have simultaneously occurred increases. The information processing apparatus determines that a Y error has occurred on the third data qubit.
