Supercurrent Time Division Multiplexing with Solid-State Integrated Hybrid Superconducting Electronics
Alessandro Paghi, Laura Borgongino, Simone Tortorella +4
Time-division multiplexing of cryogenic signals is a promising approach to reduce space requirements, shorten cooldown times, and increase the number of quantum devices measured pe…
Photonic Negative Differential Thermal Conductance Enabled by NIS Junctions
M. Pioldi, G. De Simoni, A. Braggio +1
Owing to their sensitivity to temperature fluctuations, normal metal-insulator-superconductor (NIS) junctions are leveraged in various thermal devices. This study illustrates that…
Electrostatic field-driven supercurrent suppression in ionic-gated metallic Josephson nanotransistors
Federico Paolucci, Francesco CrisÃ, Giorgio De Simoni +5
Recent experiments have shown the possibility of tuning the transport properties of metallic nanosized superconductors through a gate voltage. These results renewed the longstandin…
Cryogenic Behavior of High-Permittivity Gate Dielectrics: The Impact of the Atomic Layer Deposition Temperature and the Lithographic Patterning Method
Alessandro Paghi, Sebastiano Battisti, Simone Tortorella +2
Dielectrics featuring a high relative permittivity, i.e., high-k dielectrics, have become the standard insulators in gate architectures, enhancing the electrical performance of bot…
Estimation of the FR4 Microwave Dielectric Properties at Cryogenic Temperature for Quantum-Chip-Interface PCBs Design
Alessandro Paghi, Giacomo Trupiano, Claudio Puglia +4
Ad-hoc interface PCBs (Printed Circuit Boards) are today the standard connection between cryogenic cabling and quantum chips. Besides low-loss and low-temperature-dependent-dielect…
Back-action supercurrent diodes
Daniel Margineda, Alessandro Crippa, Elia Strambini +8
Back-action refers to a response that retro-acts on a system to tailor its properties with respect to an external stimulus. This effect is at the heart of many electronic devices s…
