Abstract
A system for measuring critical temperatures of superconducting components of a superconducting circuit housed in a cryogenic chamber with a controllable ambient temperature is described. The superconducting circuit can have a plurality of superconductor-resistor pairs connected in series. Each of the plurality of superconductor-resistor pairs can include a superconducting component and a resistor coupled in parallel with the superconducting component. The system can also include a resistance meter that measures a resistance of the superconducting circuit. The system further includes a controller that commands the cryogenic chamber to gradually sweep the ambient temperature. The controller can also record an instant ambient temperature as a critical temperature for a given superconducting component of a corresponding one of the plurality of superconductor-resistor pairs in response to detecting a change in a measured resistance across an input node and an output node of the superconducting circuit.
