摘要: A quantum computer includes a refrigeration system under vacuum including a containment vessel, a qubit chip contained within a refrigerated vacuum environment defined by the containment vessel. The quantum computer further includes a plurality of interior electromagnetic waveguides and a plurality of exterior electromagnetic waveguides. The quantum computer further includes a hermetic connector assembly operatively connecting the interior electromagnetic waveguides to the exterior electromagnetic waveguides while maintaining the refrigerated vacuum environment. The hermetic connector assembly includes an exterior multi-waveguide connector, an interior multi-waveguide connector, and a dielectric plate arranged between and hermetically sealed with the exterior multi-waveguide connector and the interior multi-waveguide connector. The dielectric plate permits electromagnetic energy when carried by the interior and exterior pluralities of electromagnetic waveguides to pass therethrough.

摘要: A microstrip that is usable in a quantum application (q-microstrip) includes a ground plane, a polyimide film disposed over the ground plane at a first surface of the polyimide film, and a conductor formed on a second side of the polyimide film such that the first surface is substantially opposite to the second surface. A material of the conductor provides greater than a threshold thermal conductivity (TH) with a structure of a dilution fridge stage (stage).

摘要: A system for transmission of quantum information for quantum error correction includes an ancilla qubit chip including a plurality of ancilla qubits, and a data qubit chip spaced apart from the ancilla qubit chip, the data qubit chip including a plurality of data qubits. The system includes an interposer coupled to the ancilla qubit chip and the data qubit chip, the interposer including a dielectric material and a plurality of superconducting structures formed in the dielectric material. The superconducting structures enable transmission of quantum information between the plurality of data qubits on the data qubit chip and the plurality of ancilla qubits on the ancilla qubit chip via virtual photons for quantum error correction.

摘要: Techniques facilitating custom thermal shields for cryogenic environments are provided. In one example, a cryostat can comprise a thermal shield extending between a thermal stage and a base structure coupled to a bottom plate of an outer vacuum chamber. The thermal stage can be coupled to a top plate of the outer vacuum chamber. The thermal shield can provide access to a sample mounting surface encompassed within the thermal shield from a region external to the outer vacuum chamber via the top and bottom plates of the outer vacuum chamber.

摘要: A device includes a first substrate formed of a first material that exhibits a threshold level of thermal conductivity. The threshold level of thermal conductivity is achieved at a cryogenic temperature range in which a quantum circuit operates. In an embodiment, the device also includes a second substrate disposed in a recess of the first substrate, the second substrate formed of a second material that exhibits a second threshold level of thermal conductivity. The second threshold level of thermal conductivity is achieved at a cryogenic temperature range in which a quantum circuit operates. In an embodiment, at least one qubit is disposed on the second substrate. In an embodiment, the device also includes a transmission line configured to carry a microwave signal between the first substrate and the second substrate.

摘要: A hybrid microwave attenuator is constructed by forming a circuit and a housing. The circuit has two ports, a resistive component configured to attenuate some frequencies in an input signal (transmitted signal), and a dispersive component configured to attenuate some frequencies within a frequency range. The resistive component and the dispersive component are arranged in a series configuration relative to one another between the two ports of the circuit. The housing includes a closable structure in which the circuit is positioned, the structure being formed of a material that exhibits at least a threshold level of thermal conductivity, where the threshold level of thermal conductivity is achieved at a cryogenic temperature range in which a quantum computing circuit operates. The housing further includes a pair of microwave connectors, the pair of connectors being thermally coupled to the housing.
