Sequential control signal generation method and device of cold ion quantum information processor

Abstract

The invention provides a sequential control signal generation method of a cold ion quantum information processor. Radio frequency signal and digital signal parameters are set through a principal computer command on a principal computer; the principal computer command is converted into a machine command which is transmitted to a sequential control FPGA; the sequential control FPGA executes the machine command and digital signals and radio frequency signals are output through a conversion module and a radio frequency synthesis module. The invention also provides a sequential control signal generation device of a cold ion quantum information processor. The device comprises a principal computer, a sequential control module, a radio frequency synthesis module and a conversion module. According to the invention, sequential control signals for experiments are described intuitively; programmed principal computer commands can be used repeatedly, so that repeated work is prevented and improvement can be made according to experiment results conveniently; the parameters such as the frequency, the phase and the amplitude of radio frequency signals can be changed conveniently; multiple paths of control signals can be controlled accurately to work cooperatively; the extendibility is great.
