Abstract: Superconducting integrated circuits may advantageously employ superconducting resonators coupled to a microwave transmission line to efficiently address superconducting flux storage devices. In an XY-addressing scheme, a global flux bias may be applied to a number of superconducting flux storage devices via a low-frequency address line, and individual superconducting flux storage devices addressed via application of high-frequency pulses via resonators driven by the microwave transmission line. Frequency multiplexing can be employed to provide signals to two or more resonators. A low-frequency current bias may be combined with a high-frequency current in one or more superconducting resonators to provide Z-addressing. A low-frequency current bias may be combined with a high-frequency current in one or more superconducting resonators to eliminate a flux bias line.

Abstract: Coaxial load pull tuners use one horizontally-only moving metallic reflective probe inserted in the slabline at fixed penetration and an adjustable RF energy absorbing eccentrically into the slabline rotated disc. The tuner does not use high precision vertical axes. The remotely adjustable attenuator is inserted adjacent to the test port and mitigates spurious high reflection. Calibration procedures using de-embedding or adapter removal techniques allow high resolution full tuner characterization in a few minutes.
