Abstract

A processing unit generates a plurality of first quantum circuits each including a quantum gate serving as a target of noise measurement and a plurality of single-qubit gates that perform a twirling operation, the first quantum circuits differing from each other in the number of repetitions of the gate operation of the quantum gate. The processing unit generates, for each of the plurality of first quantum circuits, a plurality of second quantum circuits that are quantum circuits that implement the same unitary operation and differ from each other in the number of first single-qubit gates among the plurality of single-qubit gates. The processing unit causes a quantum computer to execute the plurality of second quantum circuits, and estimates noise of the quantum gate in a state where no first single-qubit gate is included, by extrapolation based on the execution results of the plurality of second quantum circuits.
