Title:
APPLICATIONS OF SURFACE ACOUSTIC WAVE RESONATORS COUPLED TO A JOSEPHSON RING MODULATOR
Document Type and Number:
WIPO Patent Application WO/2020/025458
Kind Code:
A3
Abstract:
Superconducting device applications implemented with two surface acoustic wave resonators coupled to a Josephson ring modulator are provided. A method can include receiving, by a unitary Josephson mixer and from a first superconducting surface acoustic wave resonator of a superconducting device, a first surface acoustic wave signal that comprises one or more phonons that resonate at a first frequency, and receiving, by the unitary Josephson mixer and from a radio frequency source operatively coupled to the unitary Josephson mixer, a radio frequency control signal. The method can also include mixing the first surface acoustic wave signal and the radio frequency control signal and outputting a second surface acoustic wave signal based on mixing the first surface acoustic wave signal and the radio frequency control signal. The second surface acoustic wave signal can comprise one or more phonons that resonate at a second frequency.
