Abstract: A system includes a plurality of superconducting wires connected in parallel with one another. The plurality of superconducting wires includes a first superconducting wire and a second superconducting wire. The plurality of superconducting wires are configured to, while receiving a bias current provided to the parallel combination of the plurality of superconducting wires, operate in a superconducting state in the absence of a trigger current. The first superconducting wire is configured to, while receiving the bias current, transition to a non-superconducting state in response to receiving the trigger current. The second superconducting wire is configured to, while receiving the bias current, transition to a non-superconducting state in response to the first superconducting wire transitioning to the non-superconducting state.

Abstract: The various embodiments described herein include methods, devices, and systems for fabricating and operating superconducting circuits. In one aspect, an electric circuit includes: (1) a first superconducting component having a first terminal, a second terminal, and a constriction region between the first terminal and the second terminal; (2) a second superconducting component having a third terminal and a fourth terminal; and (3) a first electrically-insulating component that thermally couples the first superconducting component and the second superconducting component such that heat produced at the constriction region is transferred through the first component to the second superconducting component.
