Abstract

We investigate local and nonlocal signatures of hybridization between a quantum dot (QD) state and an extended Andreev bound state (ABS) in a gate-defined InAs nanowire (NW) with multiple side probes. When a QD in one of the side probes was hybridized with an ABS in the NW, a characteristic spectroscopic pattern was observed both locally, i.e., in the probe with the QD, and nonlocally, in the tunnel conductance of a remote probe. Nonlocal signatures of hybridization reveal the extended nature of the ABS.
