Signal generator circuit for a quantum computer control device

A quantum computer control system for controlling a quantum computer, comprising plurality of a quantum computer control devices,

• wherein each quantum computer control device comprises a signal generator circuit, and wherein the signal generator circuit comprises:
• a digital signal generating module which is configured to generate a digital signal, wherein the digital signal generating module comprises an arbitrary waveform generator unit, AWG unit, implemented in an FPGA or ASIC;
• a digital-to-analog converter, DAC, which is configured to convert the digital signal to an analog signal;
• and
• a digital oscilloscope unit which is coupled between the digital signal generating module and the DAC, wherein the digital oscilloscope unit is configured to record at least a part of the digital signal before the DAC converts the digital signal to the analog signal,
• wherein the digital oscilloscope unit is further configured to add an absolute or trigger-based time signature to the recorded digital signal,
• wherein the quantum computer control system further comprises a central control unit comprising a synchronization device circuit and a plurality of input channels connected to qubit readout instruments and a plurality of output channels connected to the quantum computer control devices;
• wherein the central control unit is configured to receive a recorded digital signal and/or parameters of a recorded digital signal from one or more signal generator circuits of the quantum computer control devices;
• and
• wherein the central control unit is further configured to analyze the received recorded digital signals and/or the parameters of the recorded digital signals.
