Quantum phase slips in a resonant Josephson junction
Tereza Vakhtel, Bernard van Heck
We investigate the consequences of resonant tunneling of Cooper pairs on the quantum phase slips occurring in a Josephson junction. The amplitude for quantum tunneling under the Jo…
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…
Magnetic cooling and vibration isolation of a sub-kHz mechanical resonator
Bernard van Heck, Tim Fuchs, Jaimy Plugge +2
We report recent progress towards the realization of a sub-mK, low-vibration environment at the bottom stage of a dry dilution refrigerator for use in mechanical tests of quantum m…
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…
Gate-tunable kinetic inductance in proximitized nanowires
Lukas Johannes Splitthoff, Arno Bargerbos, Lukas Grünhaupt +6
We report the detection of a gate-tunable kinetic inductance in a hybrid InAs/Al nanowire. For this purpose, we have embedded the nanowire into a quarter-wave coplanar waveguide re…
