Abstract

Reduction in circuit implementation scale is achieved.A control apparatus (10) includes a digital processing circuit (10a) and a digital-to-analog converter (DAC) (30). The digital processing circuit (10a) generates a control command group (g1) including a plurality of first control commands for controlling a plurality of first qubits, and a control command group (g2) including a plurality of second control commands for controlling a plurality of second qubits, each of the second control commands having the same frequency as that of a corresponding one of the first control commands. In addition, the digital processing circuit (10a) performs frequency-multiplexing on control command groups (g11, g12) of different frequency bands by adding offsets to the control command groups (g1, g2), to generate a digital multiplexed signal (dm1). The DAC (30) performs digital-to-analog conversion on the digital multiplexed signal (dm1), to generate an analog multiplexed signal (am1).
