Description

[Step S4] The DAC 30 performs a digital-to-analog conversion of the digital multiplexed signal dm1 to generate an analog multiplexed signal am1. Thus, the control device 10 applies a frequency offset to multiple control command groups of the same frequency band to convert them to different frequency bands before digitally multiplexing them. Furthermore, it uses a common DAC 30 for generating multiple control signals of the same frequency band to control the qubits from the control commands. [Step S6b] The analog processing circuit 10b1 modulates the second frequency band (f1+Δ-f2+Δ) of the control command signal sc2 to the third frequency band (f3-f4) to generate the control signal sd2 (second control signal) and output it to the quantum computer 6. In this way, control command signals sd1 and sd2 having the same third frequency band (f3-f4) are output.
