Gate-tunable transmons (gatemons) employing semiconductor Josephson junctions have
recently emerged as building blocks for hybrid quantum circuits. In this study, we present a …

Many important phenomena in quantum devices are dynamic, meaning that they cannot be
studied using time-averaged measurements alone. Experiments that measure such transient …

Andreev spin qubits have recently emerged as an alternative qubit platform with realizations
in semiconductor–superconductor hybrid nanowires. In these qubits, the spin degree of …

We realize a hybrid superconductor-semiconductor transmon device in which the
Josephson effect is controlled by a gate-defined quantum dot in an In As-Al nanowire …

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 …

The density of quasiparticles typically observed in superconducting qubits exceeds the
value expected in equilibrium by many orders of magnitude. Can this out-of-equilibrium …

Andreev (or superconducting) spin qubits (ASQs) have recently emerged as a promising
qubit platform that combines superconducting circuits with semiconductor spin degrees of …

Majorana bound states (MBSs) are quasiparticles that are their own antiparticles. They are
predicted to emerge as zero-energy modes localized at the boundary of a topological …

The fusion of non-Abelian anyons or topological defects is a fundamental operation in
measurement-only topological quantum computation. In topological superconductors, this …

Hybrid superconductor-semiconductor devices offer highly tunable platforms, potentially
suitable for quantum technology applications, that have been intensively studied in the past …
