Non-transitory computer-readable recording medium storing simulation program, simulation method, and information processing device

Abstract

An information processing device configured to execute processing including: generating qubit information indicating a two-dimensional lattice in which data qubits and auxiliary qubits are alternately arranged in a row and column direction; setting, for the qubit information, error information indicating error occurrence in a first data qubit among the data qubits; setting, for the qubit information, error detection information by inverting, from an initial value, a state of an auxiliary qubit adjacent to the first data qubit in the row or column direction; setting, for the qubit information, error correction information indicating a second data qubit to be corrected by a surface code using the error detection information; and determining presence or absence of occurrence of a logical error, based on a number of data qubits each of which corresponds to any one of the first or second data qubit in one row or one column in the two-dimensional lattice.
