Broadband microwave spectroscopy of semiconductor nanowire-based Cooper-pair transistors
Alex Proutski, Dominique Laroche, Bas van 't Hooft +4
The Cooper-pair transistor (CPT), a small superconducting island enclosed between two Josephson weak links, is the atomic building block of various superconducting quantum circuits…
Observation of 2e-periodic Supercurrents in Nanowire Single-Cooper-Pair Transistors
Jasper van Veen, Alex Proutski, Torsten Karzig +7
Parity control of superconducting islands hosting Majorana zero modes (MZMs) is required to operate topological qubits made from proximitized semiconductor nanowires. We, therefore…
Observation of the 4-periodic Josephson effect in indium arsenide nanowires
Dominique Laroche, Daniël Bouman, David J. van Woerkom +9
Quantum computation by non-Abelian Majorana zero modes (MZMs) offers an approach to achieve fault tolerance by encoding quantum information in the non-local charge parity states of…
Josephson radiation and shot noise of a semiconductor nanowire junction
David J. van Woerkom, Alex Proutski, Ruben J. J. van Gulik +6
We measured the Josephson radiation emitted by an InSb semiconductor nanowire junction utilizing photon assisted quasiparticle tunneling in an AC-coupled superconducting tunnel jun…
Microwave spectroscopy of spinful Andreev bound states in ballistic semiconductor Josephson junctions
David J. van Woerkom, Alex Proutski, Bernard van Heck +7
The superconducting proximity effect in semiconductor nanowires has recently enabled the study of new superconducting architectures, such as gate-tunable superconducting qubits and…
