Selective magnetic shielding of one bi-SQUID sub-loop cuts hysteresis and improves linearity above 70 K with lower cooling burden.
Using spin-triplet superconductors in Josephson junctions cuts qubit energy loss and extends coherence time for quantum information storage.
A ground-plane connection placed near the standing-wave electric-field node suppresses slot-line crosstalk while preserving qubit frequency stability.
A transferred contact layer with insulated conductive lines avoids metallization damage in layered materials while preserving superconducting behavior.
A Josephson junction uses selective ion irradiation on a thinned central barrier to boost normal resistance while maintaining superconducting properties.
