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…
Bidirectional microwave-optical conversion with an integrated soft-ferroelectric barium titanate transducer
Charles Möhl, Annina Riedhauser, Max Glantschnig +7
Efficient, low-noise, and high-bandwidth transduction between optical and microwave photons is key to long-range quantum communication between distant superconducting quantum proce…
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…
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…
