Abstract
The various embodiments described herein include methods, devices, and systems for fabricating and operating superconducting switch devices. In one aspect, an electrical circuit includes: (1) a switch device configured to switch between an on state and an off state in response to a first voltage, the switch device comprising: (a) a superconductor layer adapted to transition from a superconducting state to an insulating state in response to a first strain; and (b) a piezoelectric layer positioned adjacent to the superconductor layer, the piezoelectric layer configured to apply the first strain to the superconductor layer in response to the first voltage; (2) a voltage source electrically coupled to the piezoelectric layer of the switch device and configured to supply the first voltage; and (3) an output component coupled to the superconductor layer of the switch device.
