Abstract: A control signal transmission device for a quantum computer is provided. The control signal transmission device includes a laser source, a digital-to-analog converter (DAC), an electro-optic modulation circuit, an optical fiber, an optic-electro demodulation circuit and a plurality of qubits. The laser source provides a light. The DAC provides a plurality of first control signals. The electro-optic modulation circuit integrates the corresponding first control signals into the light to generate an optical signal, and provides the optical signal to the optical fiber. The optic-electro demodulation circuit converts and splits the optical signal into a plurality of second control signals. The optic-electro demodulation circuit transmits the second control signals to the corresponding qubits. The qubits are controlled by the corresponding second control signals. An ambient temperature set by the optic-electro demodulation circuit and the qubits is much lower than a preset temperature value.
