Claim 14:
15. A method of simulating, by a non-quantum computer, a quantum computing system having an error correction function, the method comprising:
generating, by the non-quantum computer, a quantum information density matrix;
applying, by the non-quantum computer, a selected one quantum gate to the quantum information density matrix in units of a unit time;
sequentially selecting, by the non-quantum computer, quantum gates and applying the selected quantum gates to the quantum information density matrix in units of the unit time; and
calculating, by the non-quantum computer, a change in reliability of the unit time of the quantum information density matrix as the quantum gates are applied; and
performing, by the non-quantum computer, quantum error correction in the simulated quantum computing system based on the calculated change in reliability,
wherein the performing quantum error correction includes
performing, by the non-quantum computer, quantum error correction decoding on coded quantum information corresponding to the quantum information density matrix,
applying, by the non-quantum computer, a quantum operation opposite to each of types of errors that are determined based on the calculated change in reliability; and

wherein the applying the selected one quantum gate includes shortening the unit time to improve at least one of a resolution, an accuracy, or a reliability of time for error correction decoding that is performed by the simulated quantum computing system.
