Quantum computing program, quantum computing method, and information processing device

Abstract

The present invention reduces errors caused by a variety of noise.　An information processing device (10) acquires a plurality of equivalent circuits (2a, 2b, ...) that are equivalent to two-qubit gates (1a to 1f) included in a first quantum circuit (1) and are generated with the use of each of a plurality of MS gates (3a, 3b, ...) that have different parameter values. The information processing device (10) generates a plurality of second quantum circuits (4a, 4b, ...) by converting the two-qubit gates (1a to 1f) included in the first quantum circuit (1) to the plurality of equivalent circuits (2a, 2b, ...). The information processing device (10) causes a quantum computer to execute quantum computing in accordance with the generated plurality of second quantum circuits (4a, 4b, ...). The information processing device (10) outputs, as a calculation result of the first quantum circuit (1), a value obtained by averaging the results of quantum computing of the plurality of second quantum circuits (4a, 4b, ...).
