1. A circuit comprising:
a direct current circuit that comprises a bandstop circuit that transmits a direct current, wherein the bandstop circuit comprises a bandstop filter that transmits the direct current and blocks microwave signals that are within a bandwidth range of a superconducting device;
a microwave circuit that comprises a bandpass circuit that transmits a microwave signal, wherein the bandpass circuit comprises a bandpass filter that transmits microwave signals that are within a microwave bandwidth range of a superconducting circuit and blocks the direct current; and
a common circuit that transmits the direct current and the microwave signal, wherein a first end of the common circuit is coupled to a first end of the direct current circuit and to a first end of the microwave circuit.
