Full Shapiro spectroscopy of current-phase relationships
Maxim Tjøtta, Devashish Shah, Kanishk Modi +4
Extracting the current-phase relationship (CPR) of a single superconducting junction is challenging in practice and traditionally involves embedding the junction in a larger superc…
Subgap transport in superconductor--semiconductor hybrid islands: Weak and strong coupling regimes
Marco Valentini, Rubén Seoane Souto, Maksim Borovkov +5
Superconductor--semiconductor hybrid systems play a crucial role in realizing nanoscale quantum devices, including hybrid qubits, Majorana bound states, and Kitaev chains. For such…
A gate tunable transmon qubit in planar Ge
Oliver Sagi, Alessandro Crippa, Marco Valentini +10
Gate-tunable transmons (gatemons) employing semiconductor Josephson junctions have recently emerged as building blocks for hybrid quantum circuits. In this study, we present a gate…
Tuning the Josephson diode response with an ac current
Rubén Seoane Souto, Martin Leijnse, Constantin Schrade +3
Josephson diodes are superconducting elements that show an asymmetry in the critical current depending on the direction of the current. Here, we theoretically explore how an altern…
