Methods and devices for impedance multiplication

Abstract

An example electric circuit includes a superconducting component having a first terminal and a second terminal, the superconducting component including a first portion, a second portion, and a third portion electrically connecting the first portion with the second portion. The example circuit also includes an electrically-insulating component that thermally couples the first portion with the second portion such that heat produced in response to the first portion transitioning to a non-superconducting state is transferred through the electrically-insulating component to the second portion. The example circuit further includes an input component coupled to the first portion, the input component configured to supply an input to the first portion, and an output component coupled to the second terminal of the superconducting component, the output component configured to be responsive to a voltage drop across the superconducting component.
