1. A circuit, comprising:
a first component configured to perform a particular operation;
a plurality of superconducting wires thermally coupled to the first component, wherein the superconducting wires of the plurality of superconducting wires are arranged and configured such that a threshold superconducting current for each superconducting wire is dependent on an amount of heat received from the first component;
a dielectric material separating the plurality of superconducting wires from one another, wherein a superconducting wire nearest the first component among the plurality of superconducting wires is further than a phonon mean free path of the dielectric material from the first component;
a second component configured to perform the particular operation, wherein the plurality of superconducting wires is positioned and configured to determine a first amount of heat generated by the first component and a second amount of heat generated by the second component; and
control circuitry electrically coupled to the plurality of superconducting wires and configured to:
provide current to each of the plurality of superconducting wires; and
selectively operate the first component and the second component based on the first and second amounts of heat.
