Abstract
The various embodiments described herein include methods, devices, and systems for fabricating and operating superconducting circuitry. In one aspect, an electronic system includes: (1) a first circuit that includes a plurality of superconducting wires connected in parallel with one another, the plurality of superconducting wires including: (a) a first superconducting wire with a corresponding first threshold superconducting current; and (b) a second superconducting wire; (2) a second circuit connected in parallel to the first circuit; (3) a first current source coupled to the first superconducting wire and configured to selectively supply a first current; and (4) a second current source coupled to a combination of the first circuit and the second circuit and configured to supply a second current such that the plurality of superconducting wires operate in a superconducting state; where a combination of the first current and the second current exceeds the first threshold superconducting current.
