Claim 0:
1. A method, comprising:
forming on a substrate a superconducting flux bias circuit comprising a flux controlled qubit device and a biasing loop comprising a first critical temperature material and a second critical temperature material, wherein the first critical temperature material is configured to become superconducting in response to a first temperature of the first critical temperature material being below a first critical temperature, wherein the second critical temperature material is configured to become superconducting in response to a second temperature of the second critical temperature material being below a second critical temperature, wherein the second critical temperature is lower than the first critical temperature, and wherein an entirety of a first cross-sectional portion of the biasing loop comprises the second critical temperature material;
forming a heating device on the substrate, wherein a heating element of the heating device is coupled to the first cross-sectional portion of the biasing loop; and
forming a pocket in the substrate under the first cross-sectional portion of the biasing loop and the heating element of the heating device.
