Abstract
A device for generating a qubit control signal includes: a first signal envelope generator circuit including a first multiple of signal sources, in which an output of each signal source of the first multiple of signal sources is combined to provide a first cumulative output; and a first mixer circuit coupled to the first signal envelope generator circuit, in which the first cumulative output is coupled to a first input of the first mixer circuit, and an output of the first mixer circuit includes a first qubit control signal.
Claims20
A quantum computing system comprising:
- a cooling device capable of providing a plurality of cooling stages, wherein each cooling stage is maintained at a different temperature;
- a qubit chip comprising a qubit, wherein the qubit chip is arranged in the cooling device and maintained at a first cooling stage, wherein a temperature of the first cooling stage is between 0 K and 100 mK;
- and
- a control circuit for generating a qubit XY control signal arranged in the cooling device and maintained at a second cooling stage, wherein a temperature of the second cooling stage is above the temperature of the first cooling stage and below room temperature, and wherein the control circuit is coupled to qubit chip.
