The quantum circuit learning device includes a signal input unit that provides a quantum circuit including plural quantum bits with an input signal, a signal acquisition unit that observes states of quantum bits that the quantum circuit includes and acquires an output signal based on the observed states, and an adjustment unit that adjusts a circuit parameter that defines a circuit configuration of the quantum circuit, using an output signal that the signal acquisition unit acquires and a cost function that is set based on a teacher signal corresponding to the output signal.
