US 12,648,367 B1 · Superconducting device with asymmetric impedance

Abstract

An electronic component having an asymmetric impedance is provided. The component includes first, second and third branches that connect at a common node. The component includes a first portion of superconducting material disposed along the first branch and a second portion of superconducting material disposed along the second branch. The component includes a first device disposed along the first branch and configured to transition the second portion of the superconducting material to a non-superconducting state when a current between a first terminal of the first device and a second terminal of the first device exceeds a first threshold value and a second device disposed along the second branch and configured to transition the first portion of the superconducting material to a non-superconducting state when a current between a first terminal of the second device and a second terminal of the second device exceeds a second threshold value.

Dependent claims

A diode device, comprising:

a resistive component coupled to a first terminal;
and
a superconducting component coupled in series between the resistive component and a second terminal;
wherein, under a predefined range of operating conditions:
a current having a first value supplied to the second terminal causes the superconducting component to transition to a non-superconducting state;
and
the current having the first value supplied to the first terminal does not cause the superconducting component to transition to the non-superconducting state such that the diode device has a different impedance between the first terminal and the second terminal as compared to an impedance between the second terminal and the first terminal.
