Information processing device, method, and non-transitory computer-readable recording medium storing program

Abstract

An information processing device includes: a plurality of qubits; a generator that generates a plurality of signals; a converter that converts the plurality of signals into a plurality of analog signals of which signal levels are regulated; a multiplexer that outputs a multiplexed signal obtained by multiplexing the plurality of analog signals; a divider that divides the multiplexed signal into a plurality of divided signals; a plurality of attenuators that attenuates the plurality of divided signals and provides the plurality of attenuated divided signals to each of the plurality of qubits; and a setter that sends setting signals that are common to the plurality of attenuators and indicate each of attenuation amounts of the plurality of attenuators, wherein the attenuation amounts are set in the plurality of attenuators, based on the setting signals.
