Finite Length Effects and Coulomb Interaction in Ge Quantum Well-Based Josephson Junctions Probed with Microwave Spectroscopy
S. C. ten Kate, D. C. Ohnmacht, M. Coraiola +10
Proximitized Ge quantum wells have emerged as a novel platform for studying Andreev bound states (ABSs), due to their expected strong spin-orbit interaction and high mobility. Here…
Development of a Nb-based semiconductor-superconductor hybrid platform
Sjoerd Telkamp, Tommaso Antonelli, Clemens Todt +12
Semiconductor-superconductor hybrid materials are used as a platform to realise Andreev bound states, which hold great promise for quantum applications. These states require transp…
Direct microwave spectroscopy of Andreev bound states in planar Ge Josephson junctions
M. Hinderling, S. C. ten Kate, M. Coraiola +7
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…
Spin-degeneracy breaking and parity transitions in three-terminal Josephson junctions
M. Coraiola, D. Z. Haxell, D. Sabonis +7
Harnessing spin and parity degrees of freedom is of fundamental importance for the realization of emergent quantum devices. Nanostructures embedded in superconductor--semiconductor…

We perform switching current measurements of planar Josephson junctions (JJs) coupled by a common superconducting electrode, with independent control over the two superconducting p…
Zeeman and Orbital Driven Phase Transitions in Planar Josephson Junctions
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,…

We demonstrate a flip-chip-based approach to microwave measurements of Andreev bound states in a gate-tunable planar Josephson junction using inductively-coupled superconducting lo…
Microwave-induced conductance replicas in hybrid Josephson junctions without Floquet-Andreev states
D. Z. Haxell, M. Coraiola, D. Sabonis +9
Light-matter interaction enables engineering of non-equilibrium quantum systems. In condensed matter, spatially and temporally cyclic Hamiltonians are expected to generate energy-p…

On the Role of Out-of-Equilibrium Phonons in Gated Superconducting Switches
M. F. Ritter, N. Crescini, D. Z. Haxell +5
Recent experiments suggest the possibility to tune superconductivity in metallic nanowires by application of modest gate voltages. It is largely debated whether the effect is due t…
