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…
Magnetically Induced Switching-Current Jumps in InAs/Al Josephson Junctions
Ofelia Durante, Roberta Citro, Elia Strambini +8
We report Barkhausen-like switching at millitesla fields in an -doped InAs/Al nanowire Josephson junction, which serves as an interferometric probe of intrinsic magnetic reconfi…
A Kapitza Pendulum Route to Supercurrent Tunnel Diodes
Yuriy Yerin, Stefan-Ludwig Drechsler, A. A. Varlamov +3
Superconducting diodes that support nonreciprocal supercurrent flow in principle constitute attractive, non-dissipative, circuit elements for superconducting electronics. But their…
Highly-linear flux-to-voltage transducer based on superconducting quantum interference proximity transistors
Angelo Greco, Giorgio De Simoni, Francesco Giazotto
Superconducting quantum interference devices (SQUIDs) are state-of-the-art in ultra-sensitive magnetometry; however, conventional SQUID devices are fundamentally limited by the inh…
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…
Active electron cooling of graphene
Federico Paolucci, Federica Bianco, Francesco Giazotto +1
In the emergent field of quantum technology, the ability to manage heat at the nanoscale and in cryogenic conditions is crucial for enhancing device performance in terms of noise,…
