Abstract: This application discloses a clock synchronization system, including a quantum control processor (QCP) and N digital/analog mutual conversion devices, each digital/analog mutual conversion device including a frequency conversion module and a signal synchronization module that includes a D flip-flop (DFF). The QCP generates a global synchronization signal and reference clock signals; and transmits the global synchronization signal and a reference clock signal to the frequency conversion module and transmits the global synchronization signal to the signal synchronization module of each conversion device. The frequency conversion module performs frequency conversion processing on the reference clock signal to obtain a target clock signal, and generates a signal synchronization instruction according to the global synchronization signal; and transmits the signal synchronization instruction and the target clock signal to the signal synchronization module.

Abstract: In a waveform data transmission method, control and measurement waveform data of a first signal waveform for control and measurement of a quantum chip is generated by control and measurement software of a qubit control and measurement system. The control and measurement waveform data is compressed, by the control and measurement software, to obtain compressed control and measurement waveform data. The compressed control and measurement waveform data is transmitted to an electronics system of the qubit control and measurement system. The compressed control and measurement waveform data is decompressed, by processing circuitry of the electronics system, to obtain recovered control and measurement waveform data. The first signal waveform is transmitted to the quantum chip according to the recovered control and measurement waveform data.
