Abstract: Un dispositivo de acoplamiento superconductor incluye una estructura de resonador. La estructura de resonador tiene un primer extremo configurado para acoplarse a un primer dispositivo y un segundo extremo configurado para acoplarse a un segundo dispositivo. El dispositivo incluye además un sistema de electrones acoplado a la estructura de resonador y una compuerta colocada proximal a una porción del sistema de electrones. El sistema de electrones y la compuerta se configuran para interrumpir la estructura de resonador en una o más ubicaciones predeterminadas formando un conmutador. La puerta se configura para recibir un voltaje de compuerta y variar una inductancia del sistema de electrones con base en el voltaje de compuerta. La variación de la inductancia induce que la estructura de resonador varíe la fuerza de acoplamiento entre el primer dispositivo y el segundo dispositivo.

Abstract: A system for optical transduction of quantum information includes a qubit chip including a plurality of data qubits configured to operate at microwave frequencies, and a transduction chip spaced apart from the qubit chip, the transduction chip including a microwave-to-optical frequency transducer. The system includes an interposer coupled to the qubit chip and the transduction chip, the interposer including a dielectric material including a plurality of superconducting microwave waveguides formed therein. The plurality of superconducting microwave waveguides is configured to transmit quantum information from the plurality of data qubits to the microwave-to-optical frequency transducer on the transduction chip, and the microwave-to-optical frequency transducer is configured to transduce the quantum information from the microwave frequencies to optical frequencies.

Abstract: A quantum computing device is fabricated by forming, on a superconductor layer (410), a first resist pattern defining a device region and a sensing region within the device region. The superconductor layer within the sensing region is removed, exposing a region of a first surface of an underlying semiconductor layer (340) outside the device region. The exposed region of the semiconductor layer is implanted, forming an isolation region surrounding the device region. The sensing region and a portion of the device of the superconductor layer are exposed. A sensing region contact (202) is formed by coupling the first surface of the semiconductor layer with a first metal layer. A nanorod contact (206, 212) using the first metal within the portion of the device region outside the sensing region is formed. By depositing a second metal layer on a second surface of the semiconductor layer within the sensing region, a tunnel junction gate (204) is formed.

Abstract: A superconducting coupling device includes a resonator structure. The resonator structure has a first end configured to be coupled to a first device and a second end configured to be coupled to a second device. The device further includes an electron system coupled to the resonator structure, and a gate positioned proximal to a portion of the electron system. The electron system and the gate are configured to interrupt the resonator structure at one or more predetermined locations forming a switch. The gate is configured to receive a gate voltage and vary an inductance of the electron system based upon the gate voltage. The varying of the inductance induces the resonator structure to vary a strength of coupling between the first device and the second device.
