Abstract: A superconducting quantum interference device (SQUID) array (SQA) includes at least one row each including SQUIDs. The SQUIDs in each row are connected in parallel and include junctions, such as Josephson junctions, shared among the SQUIDs. The SQUIDs have respective inductance parameters and the junctions have respective critical currents. The respective inductance parameters of the SQUIDs and respective critical currents of the junctions both vary in a predetermined pattern across the row. This improves performance including improved linearity and improved sensitivity.

Abstract: Proposed is a phase shift introduction method, a structure, and a circuit device for eliminating or minimizing a risk associated with dissimilar materials, solving in principle a problem of mixing of a signal current and a control current that occurs due to DC connection of a phase shifter to a signal line, and stably and reliably providing a phase shift that is desired to be introduced without being adversely effected by noise generated by an ambient magnetic field, which is generated due to use of an external power supply. A structure according to the present invention includes a phase shifter 101 and a closed-loop circuit 103 that is directly used for computation or storage, and a quantum phase shift is generated in the closed-loop circuit 103 by using a fractional flux quantum captured by the phase shifter 101 that is DC-separated from the closed-loop circuit 103.

Abstract: A hybrid Bacon-Shor surface code is implemented using a fault tolerant quantum computer comprising hybrid acoustic-electric qubits. A control circuit includes an asymmetrically threaded superconducting quantum interference devices (ATS) that excites phonons in a mechanical resonator by driving a storage mode of the mechanical resonator and dissipates phonons from the mechanical resonator via an open transmission line coupled to the control circuit. The hybrid Bacon-Shor surface code only couples four phononic modes per given ATS, reducing cross-talk as compared to other systems that couple more phononic modes per ATS. Also, measurements are performed such that three parity measurements are taken between a phononic readout mode and a transmon qubit in a given syndrome measurement cycle.

Abstract: A superconducting readout system employing a microwave transmission line, and a microwave superconducting resonator communicatively coupled to the microwave transmission line, and including a superconducting quantum interference device (SQUID), may be advantageously calibrated at least in part by measuring a resonant frequency of the microwave superconducting resonator in response to a flux bias applied to the SQUID, measuring a sensitivity of the resonant frequency in response to the flux bias, and selecting an operating frequency and a sensitivity of the microwave superconducting resonator based at least in part on a variation of the resonant frequency as a function of the flux bias. The flux bias may be applied to the SQUID by an interface inductively coupled to the SQUID. Calibration of the superconducting readout system may also include determining at least one of a propagation delay, a microwave transmission line delay, and a microwave transmission line phase offset.
