[Th-A2-H-01 (Invited)] Tunnel spectroscopy of Andreev Bound states in single and coupled Josephson junctions

We study Andreev bound states in Josephson junctions on InAs–Al devices using tunnel spectroscopy. The spectra in two junctions sharing a superconducting electrode reveal coherent coupling of the states. We also performed the nonlocal tunnel spectroscopy of a single junction.
