Abstract
A technique relates to a superconducting device. A gyrator includes a first mixing device coupled to a second mixing device. A lumped-element resistor is connected in parallel to the gyrator.
Claims12
A method of forming a superconducting device comprising:
- forming a gyrator including a first mixing device coupled to a second mixing device;
- and
- coupling a lumped-element resistor in parallel to the gyrator.
A method of fabricating a superconducting device comprising:
- providing a first mixing device having a first mixing port and a second mixing port and a second mixing device having another first mixing port and another second mixing port, the first and second mixing devices being superconducting three-wave mixing devices;
- coupling the second mixing port and the another second mixing port together via a delay line to form a gyrator;
- and
- coupling a lumped-element resistor in parallel to the gyrator.

A method of operating a superconducting isolator comprising:
- receiving a signal at a first mixing device coupled to a second mixing device, the first and second mixing devices being coupled in parallel to a lumped-element resistor;
- and
- outputting the signal from the second mixing device, wherein any signal received at the second mixing device is blocked from being output from the first mixing device.
