Nonlocal signatures of hybridization between quantum dot and Andreev bound states

Understand

We investigate local and nonlocal signatures of hybridization between a quantum dot state and an extended Andreev bound state (ABS) in a gate-defined InAs nanowire with multiple side probes.

• When a quantum dot in one of the side probes was hybridized with an ABS in the nanowire, a characteristic spectroscopic pattern was observed both locally, i.e., in the probe with the quantum dot, and nonlocally, in the tunnel conductance of a remote probe.
• Nonlocal signatures of hybridization reveal the extended nature of the ABS.
