Abstract We investigate superconducting hybrid nanowires defined by patterned gates on a two-dimensional heterostructure of InAs and Al, with lateral quantum dots operating as single-level spectrometers along the side of the nanowire. Applying magnetic field along the wire axis spin splits dot levels, providing spin-resolved spectroscopy. We investigate spin and charge polarizations of subgap states in the nanowire and their evolution with magnetic field and gate voltage.

Abstract We investigate a semiconductor nanowire-based gatemon qubit with epitaxial Al on two facets of the nanowire, allowing gate control of wire density. Two segments have the Al removed, one forming a Josephson junction, and the other operating as a transistor, providing in situ switching between dc transport and qubit operation. Gating the nanowire (NW) changes the rate of decay of qubit frequency in magnetic field applied parallel to the NW.
