Abstract The observation of the gate-controlled supercurrent (GCS) effect in superconducting nanostructures increased the hopes for realizing a superconducting equivalent of semiconductor field-effect transistors. However, recent works attribute this

Abstract Controlled coupling between distant particles is a key requirement for the implementation of quantum information technologies. A promising platform are hybrid systems of semiconducting quantum dots coupled to superconducting islands, where t

Abstract Hybrid nanostructures consisting of two parallel InAs nanowires connected by an epitaxially grown superconductor (SC) shell recently became available. Due to the defect-free SC-semiconductor interface and the two quasi-one-dimensional channe

The fate of Yu-Shiba-Rusinov states in the presence of a strong Coulomb repulsion in a superconductor remains unknown. Here, the authors couple a quantum dot to a superconducting island with a tunable Coulomb repulsion, where they find a singlet many

Abstract Little–Parks oscillations of a hollow superconducting cylinder are of interest for flux-driven topological superconductivity in single Rashba nanowires. The oscillations are typically symmetric in the orientation of the applied magnetic fl

Local magnetic moments coupled to superconductors can form subgap Yu-Shiba-Rusinov states. Here the authors show that Shiba states made with an InAs nanowire quantum dot have large spatial extent, which is beneficial for making Shiba chains that are

The interplay of induced superconductivity and magnetic fields should drive InAs nanowires into a topological superconducting phase. Laroche et al. use the microwave radiation emitted by an InAs nanowire Josephson junction to observe the 4π-periodic

Cooper pair splitting (CPS) is a way to create spatially separated, entangled electron pairs. To this day, CPS is often identified in experiments as a spatial current correlation. However, such correlations can arise even in the absence of CPS, when

We characterize parallel double quantum dot Josephson junctions based on closely spaced double nanowires bridged by in-situ deposited superconductors. The parallel double dot behavior occurs despite the proximity of the two nanowires and the potentia

Forskning – og i det hele taget det at tilvejebringe og dele ny viden – er et helt centralt værktøj i Realdanias værktøjskasse, særligt når det handler om at løse nogle af de mere komplekse samfundsproblemer. Det er afgørende, at vi gener
