A semiconducting nanowire fully wrapped by a superconducting shell has been proposed
as a platform for obtaining Majorana modes at small magnetic fields. In this study, we …

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 …

Connecting double quantum dots via a semiconductor-superconductor hybrid segment
offers a platform for creating a two-site Kitaev chain that hosts Majorana zero modes at a …

Theoretical descriptions of Yu-Shiba-Rusinov (YSR) states induced by magnetic impurities
inside the gap of a superconductor typically rely on a classical spin model or are restricted to …

We present transport spectroscopy of subgap states in a bottom gated InAs nanowire
coupled to a normal lead and a superconducting aluminium lead. The device shows clearly …

Magnetic impurities embedded in a metal are screened by the Kondo effect, signaled by the
formation of an extended correlation cloud, the so-called Kondo or screening cloud. In a …

Magnetic adatoms on a superconducting substrate undergo a quantum phase transition as
their exchange coupling to the conduction electrons increases. For quantum spins, this …

We demonstrate the Josephson effect in a serial double quantum dot defined in a nanowire
with epitaxial superconducting leads. The supercurrent stability diagram adopts a …
