Quantum circuit learning device, quantum circuit learning method, computer program, and recording medium

摘要

Provision of quantum circuit learning device, quantum circuit learning method, computer program, and recording medium. A signal input unit that gives an input signal to a quantum circuit having a plurality of quantum bits, a signal acquisition unit that observes the state of the quantum bits included in the quantum circuit, and acquires an output signal based on the observed state, and the signal. It includes an adjustment unit that adjusts circuit parameters that define the circuit configuration of the quantum circuit by using a cost function set based on the output signal acquired by the acquisition unit and the teacher signal for the output signal.
