A Zero-Bias Superconducting Voltage Amplifier Based on the Bipolar Thermoelectric Effect
Giacomo Trupiano, Giorgio De Simoni, Francesco Giazotto
We introduce a zero-bias superconducting voltage amplifier that harvests energy from a thermal gradient by exploiting negative differential resistance (NDR) in an asymmetric tunnel…
Highly-Linear Proximity-Based Bi-SQUID Operating above 4 K
G. Trupiano, E. Riccardi, C. Puglia +5
We demonstrate a highly linear superconducting quantum interference device (SQUID) amplifier based on a double-loop (Bi-SQUID) architecture incorporating three superconductor-norma…
A Thermally Modulated SINIS Trasconductance Amplifier
Giacomo Trupiano, Giorgio De Simoni, Francesco Giazotto
We introduce a superconducting transconductance amplifier based on the thermal modulation of a SINIS (Superconductor-Insulator-Normal metal-Insulator-Superconductor) configuration.…
Josephson Field Effect Transistors with InAs on Insulator and High Permittivity Gate Dielectrics
Alessandro Paghi, Laura Borgongino, Sebastiano Battisti +6
InAs on Insulator (InAsOI) has been recently demonstrated as a promising platform to develop hybrid semiconducting-superconducting Josephson Junctions (JJs) and Josephson Field Eff…
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…
InAs on Insulator: A New Platform for Cryogenic Hybrid Superconducting Electronics
Alessandro Paghi, Giacomo Trupiano, Giorgio De Simoni +3
Superconducting circuits based on hybrid InAs Josephson Junctions (JJs) play a starring role in the design of fast and ultra-low power consumption solid-state quantum electronics a…
