Abstract

An information processing apparatus acquires measurement data indicating measurement values of quantum states of qubits measured after a quantum computer has repeatedly executed, a plurality of times, a quantum gate sequence including a plurality of quantum gates for the qubits. The information processing apparatus divides a space to which a matrix indicating a quantum operation by the quantum gate sequence belongs into a first subspace including a singular point at which eigenvalues satisfying predetermined conditions are calculated, and a second subspace that does not include the singular point, and generates, within a range of the second subspace, a function that linearly approximates an influence of an error of a quantum gate included in the plurality of quantum gates on the measurement value. The information processing apparatus estimates, by using the function and the measurement data, the error of the quantum gate when the quantum computer executes the quantum gate.
