Abstract

We characterize parallel double quantum dot Josephson junctions based on closely spaced double nanowires bridged by in-situ deposited superconductors. The parallel double dot behavior occurs despite the proximity of the two nanowires and the potential risk of nanowire clamping during growth. By tuning the charge filling and lead couplings, we map out the parallel double quantum dot Yu-Shiba-Rusinov phase diagram. Our quasi-independent two-wire hybrids show promise for the realization of exotic topological phases.
