US Patent 10565515 Quantum circuit assemblies with triaxial cables

Embodiments of the present disclosure describe quantum circuit assemblies utilizing triaxial cables to communicate signals to/from quantum circuit components. One assembly includes a cooling apparatus for cooling a quantum circuit component that includes at least one qubit device. The cooling apparatus includes at least one triaxial connector for providing signals to and/or receiving signals from the quantum circuit component using one or more triaxial cables. Other assemblies include quantum circuit components and various electronic components (e.g. attenuators, filters, or amplifiers) for use within the cooling apparatus, adapted to be used with triaxial cables by incorporating triaxial connectors as well.
