The Gain-Engineered Transmon
Ian Yang, Francesco Adinolfi, Alessandro Bruno +3
The interaction between a qubit and its environment can be engineered such that one error channel dominates over all others, resulting in noise bias. This property enables error co…
Enhancing Kerr-Cat Qubit Coherence with Controlled Dissipation
Francesco Adinolfi, Daniel Z. Haxell, Alessandro Bruno +4
Quantum computing crucially relies on maintaining quantum coherence for the duration of a calculation. Bosonic quantum error correction protects this coherence by encoding qubits i…
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…
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…
Demonstration of nonlocal Josephson effect in Andreev molecules
D. Z. Haxell, M. Coraiola, M. Hinderling +9
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,…
Control over epitaxy and the role of the InAs/Al interface in hybrid two-dimensional electron gas systems
E. Cheah, D. Z. Haxell, R. Schott +12
In-situ synthesised semiconductor/superconductor hybrid structures became an important material platform in condensed matter physics. Their development enabled a plethora of novel…
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…
Ubiquitous Superconducting Diode Effect in Superconductor Thin Films
Yasen Hou, Fabrizio Nichele, Hang Chi +13
The macroscopic coherence in superconductors supports dissipationless supercurrents which could play a central role in emerging quantum technologies. Accomplishing unequal supercur…
Semiconductor Epitaxy in Superconducting Templates

Integration of high quality semiconductor-superconductor devices into scalable and CMOS compatible architectures remains an outstanding challenge, currently hindering their practic…
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…
