Exploring the energy spectrum of a four-terminal Josephson junction: Towards topological Andreev band structures
Tommaso Antonelli, Marco Coraiola, David Christian Ohnmacht +10
Hybrid multiterminal Josephson junctions (JJs) are expected to harbor a novel class of Andreev bound states (ABSs), including topologically nontrivial states in four-terminal devic…

We demonstrate microwave measurements of the Andreev bound state (ABS) spectrum in planar Josephson junctions (JJs) defined in Ge high mobility two-dimensional hole gases contacted…
Flux-Tunable Josephson Diode Effect in a Hybrid Four-Terminal Josephson Junction
M. Coraiola, A. E. Svetogorov, D. Z. Haxell +10
We investigate the direction-dependent switching current in a flux-tunable four-terminal Josephson junction defined in an InAs/Al two-dimensional heterostructure. The device exhibi…
Flip-chip-based fast inductive parity readout of a planar superconducting island
M. Hinderling, S. C. ten Kate, D. Z. Haxell +8
Properties of superconducting devices depend sensitively on the parity (even or odd) of the quasiparticles they contain. Encoding quantum information in the parity degree of freedo…

D. Z. Haxell, M. Coraiola, D. Sabonis +7
We perform supercurrent and tunneling spectroscopy measurements on gate-tunable InAs/Al Josephson junctions (JJs) in an in-plane magnetic field, and report on phase shifts in the c…
Phase-engineering the Andreev band structure of a three-terminal Josephson junction
M. Coraiola, D. Z. Haxell, D. Sabonis +11
In hybrid Josephson junctions with three or more superconducting terminals coupled to a semiconducting region, Andreev bound states may form unconventional energy band structures,…
