APPLICATIONS OF A SUPERCONDUCTING DEVICE THAT MIXES SURFACE ACOUSTIC WAVES AND MICROWAVE SIGNALS

Superconducting device applications implemented with a surface acoustic wave resonator and a superconducting microwave resonator coupled to a Josephson ring modulator are provided. A method can comprise receiving, by a microwave Josephson mixer, and from a superconducting surface acoustic wave resonator of a superconducting device, a surface acoustic wave signal that comprises one or more phonons that resonate at a first frequency. The method can also comprise receiving, by the microwave Josephson mixer and from a superconducting microwave resonator of the superconducting device, a microwave signal that comprises one or more photons that can resonate at a second frequency. Further, the method can also comprise mixing, by the microwave Josephson mixer, the surface acoustic wave signal and the microwave signal based on a microwave control signal received from a microwave source operatively coupled to the microwave Josephson mixer.
