Superconducting diodes are proposed nonreciprocal circuit elements that should exhibit
nondissipative transport in one direction while being resistive in the opposite direction …

Sensitive microwave detectors are essential in radioastronomy, dark-matter axion searches
and superconducting quantum information science,. The conventional strategy to obtain …

A Josephson junction (JJ) is a key device for develo** superconducting circuits, wherein a
supercurrent in the JJ is controlled by the phase difference between the two …

The Josephson junction (JJ) is an essential element of superconducting (SC) devices for

We report a probable observation of the dc Josephson effect in mesoscopic junctions of
three and four superconductors. The devices are fabricated in a top-down fashion from a …

Typical superconducting materials have both time-reversal symmetry and inversion
symmetry. Devices that break these symmetries are expected to have exotic phenomena …

We introduce Weyl Josephson circuits: small Josephson junction circuits that simulate Weyl
band structures. We first formulate a general approach to design circuits that are analogous …

The Andreev bound state spectra of multi-terminal Josephson junctions form an artificial
