QUANTUM COMPUTER CONTROL DEVICE

Provided is a quantum computer control device having exceptional usability, scalability, robustness, and the like. In the present invention, a control device 110 of a quantum computer 100 comprises: a server 130 that calculates a waveform signal for controlling a quantum bit system 120 comprising a plurality of quantum bits; and a plurality of signal processing units 140-1 to 140-N that generate, on the basis of the waveform signal, electromagnetic signals to be projected to the quantum bit system. The signal processing units each comprise: a logic device that performs digital signal processing on the waveform signal to generate a baseband signal; a digital oscillator that generates an oscillation signal; a mixer that mixes the baseband signal and the oscillation signal to output a mixed signal; a DA converter that performs DA conversion on the mixed signal to obtain an analog signal; an RF circuit that generates an electromagnetic signal from the analog signal; and an AD converter that performs AD conversion on the signal input from the RF circuit.
