Graphene Josephson diodes from inherent asymmetric disorder
Ivan Villani, Luca Chirolli, Matteo Carrega +10
Josephson diodes are non-reciprocal superconducting devices characterized by different switching currents depending on the current flow direction. They recently attracted considera…
Fraxonium: Fractional fluxon states for qudit encoding
Luca Chirolli, Valentina Brosco, Uri Vool +2
We propose a superconducting circuit hosting low-lying states, well separated from the rest of the spectrum, that naturally realizes a qudit system protected from leakage error…
Perfect spin nonreciprocity in gated superconducting altermagnetic heterostructures
Pei-Hao Fu, Jun-Feng Liu, Luca Chirolli +1
We consider a superconducting altermagnet heterostructure and demonstrate that the interplay between altermagnetism and a selective filter of transverse momentum channels enables p…
Nonequilibrium Cooper quartet generation in superconducting devices
Luca Chirolli, Alessandro Braggio, Michele Governale
Cooper quartets are aggregates of four electrons that generalize the concept of Cooper pairs, and their study can unfold unexplored perspectives in correlated matter and many-body…
Multiplexed microwave resonators by frequency comb spectroscopy
Angelo Greco, Jukka-Pekka Kaikkonen, Luca Chirolli +4
Coplanar waveguide resonators are central to the thriving field of circuit quantum electrodynamics. Recently, we have demonstrated the generation of a broadband microwave-frequency…
Diode effect in the Fraunhofer pattern of disordered planar Josephson junctions
Luca Chirolli, Angelo Greco, Alessandro Crippa +4
The Josephson diode effect describes the property of a Josephson junction to have different values of the critical current for different direction of applied bias current and it is…
