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…

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…

Minimizing the discrimination time for quantum states of an artificial atom

Ivan Takmakov, Patrick Winkel, Farshad Foroughi +9

Fast discrimination between quantum states of superconducting artificial atoms is an important ingredient for quantum information processing. In circuit quantum electrodynamics, in…

Phonon traps reduce the quasiparticle density in superconducting circuits

Fabio Henriques, Francesco Valenti, Thibault Charpentier +14

Out of equilibrium quasiparticles (QPs) are one of the main sources of decoherence in superconducting quantum circuits, and are particularly detrimental in devices with high kineti…

Electrodynamics of granular aluminum from superconductor to insulator: observation of collective superconducting modes

F. Levy-Bertrand, T. Klein, T. Grenet +14

We report on a detailed study of the optical response and phase diagram ( being the superconducting critical temperature and the normal state resistivity of the fi…

Granular aluminum: A superconducting material for high impedance quantum circuits

Lukas Grünhaupt, Martin Spiecker, Daria Gusenkova +8

Superconducting quantum information processing machines are predominantly based on microwave circuits with relatively low characteristic impedance, of about 100 Ohm, and small anha…
