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.

An electrical circuit, comprising:
- a first superconducting component comprising a superconducting material having a first terminal, a second terminal, and a constriction region between the first terminal and the second terminal;
- a second superconducting component comprising a superconducting material having a third terminal and a fourth terminal;
- and
- 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 electrically-insulating component to the second superconducting component, wherein the first electrically-insulating component comprises a non-superconducting dielectric material.
