Spectroscopy of spin-split Andreev levels in a quantum dot with superconducting leads
Arno Bargerbos, Marta Pita-Vidal, Rok Žitko +9
We use a hybrid superconductor-semiconductor transmon device to perform spectroscopy of a quantum dot Josephson junction tuned to be in a spin-1/2 ground state with an unpaired qua…
Microwave spectroscopy of interacting Andreev spins
J. J. Wesdorp, F. J. Matute-Caňadas, A. Vaartjes +13
Andreev bound states are fermionic states localized in weak links between superconductors which can be occupied with spinful quasiparticles. Microwave experiments using superconduc…
Singlet-doublet transitions of a quantum dot Josephson junction detected in a transmon circuit
Arno Bargerbos, Marta Pita-Vidal, Rok Žitko +10
We realize a hybrid superconductor-semiconductor transmon device in which the Josephson effect is controlled by a gate-defined quantum dot in an InAs/Al nanowire. Microwave spectro…
Dynamical polarization of the fermion parity in a nanowire Josephson junction
J. J. Wesdorp, L. Grünhaupt, A. Vaartjes +6
Josephson junctions in InAs nanowires proximitized with an Al shell can host gate-tunable Andreev bound states. Depending on the bound state occupation, the fermion parity of the j…
