Abstract

The application provides a measurement and control system, a measurement and control method and a quantum computing device, and relates to the technical field of quantum computing. The measurement and control system comprises a quantum chip, a functional unit, an exchange unit and an upper computer. The upper computer is used for controlling the functional unit to work, and the functional unit is used for measuring and controlling quantum computing of the quantum chip. The functional unit comprises a low-noise voltage unit, an arbitrary waveform generation unit, a radio frequency arbitrary wave generation unit, a reflection measurement unit, a microwave excitation unit, a synchronous expansion unit and a fast feedback unit with a unified interface. The measurement and control method comprises the following steps: outputting a clock signal by the synchronous expansion unit in the functional unit through the upper computer; controlling the functional unit to enter a clock synchronization mode through the upper computer; outputting a synchronous trigger signal by the synchronous expansion unit through the upper computer; synchronizing the internal clock interface based on the received synchronous trigger signal and outputting a synchronous clock signal through the functional unit; and controlling the functional unit to enter a working mode through the upper computer.
