Clock synchronization apparatus and method, quantum measurement and control system, and quantum computer

Abstract

Disclosed are a clock synchronization apparatus, a clock synchronization method, a quantum measurement and control system, and a quantum computer. The clock synchronization apparatus includes a benchmark clock, a first clock generator, function boards, and second clock generators. The first clock generator is in a communication connection to the second clock generators, and one corresponding second clock generator is disposed on each of the function boards. The benchmark clock provides a first benchmark clock signal to the first clock generator providing a synchronization signal used to synchronize output clocks of all the second clock generators to the second clock generators based on the first benchmark clock signal. The second clock generators output, based on the synchronization signal, a work clock signal required by the function boards. The plurality of function boards generate, based on the work clock signal, a first signal required to perform corresponding work by using qubits.
