摘要: A superconducting device that mixes surface acoustic waves and techniques for fabricating the same are provided. A superconducting device can comprise a first surface acoustic wave resonator comprising a first low-loss piezo-electric dielectric substrate. The superconducting device can also comprise a second surface acoustic wave resonator comprising a second low-loss piezo-electric dielectric substrate. Further, the superconducting device can comprise a Josephson ring modulator coupled to the first surface acoustic wave resonator and the second surface acoustic wave resonator. The Josephson ring modulator is a dispersive nonlinear three-wave mixing element.

摘要: A cascading microwave switch (cascade) includes a set of Josephson devices, each Josephson device in the set having a corresponding operating bandwidth of microwave frequencies, wherein different operating bandwidths have different corresponding center frequencies. A series coupling is formed between first Josephson device from the set and an nth Josephson device from the set, wherein the series coupling causes the first Josephson device in an open state to reflect back to an input port of the first Josephson device a signal of a first frequency from a frequency multiplexed microwave signal (multiplexed signal) and the nth Josephson device in the open state to reflect back to an input port of the nth Josephson device a signal of an nth frequency from the multiplexed signal.

摘要: Techniques relate to an on-chip Josephson parametric converter. A Josephson ring modulator includes four nodes. A lossless on-chip flux line is capacitively coupled to two adjacent nodes of the four nodes of the Josephson ring modulator. The lossless on-chip flux line has an input port configured to receive a pump drive signal that couples differentially to the two adjacent nodes of the of the Josephson ring modulator. The pump drive signal thereby excites a common mode of the on-chip Josephson parametric converter.

摘要: 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.

摘要: A cascading selective microwave directional amplifier (cascade) includes a set of Josephson devices, each Josephson device in the set having a corresponding operating bandwidth of microwave frequencies. Different operating bandwidths have different corresponding center frequencies. A series coupling is formed between first Josephson device from the set and an nth Josephson device from the set. The series coupling causes the first Josephson device to amplify a signal of a first frequency from a frequency multiplexed microwave signal (multiplexed signal) in a first signal flow direction through the series coupling and the nth Josephson device to amplify a signal of an nth frequency in a second signal flow direction through the series, where the second signal flow direction is opposite of the first signal flow direction.
