Josephson parametric amplifier with Chebyshev gain profile and high saturation
Ryan Kaufman, Theodore White, Mark I. Dykman +10
We demonstrate a Josephson parametric amplifier design with a band-pass impedance matching network based on a third-order Chebyshev prototype. We measured eight amplifiers operatin…
Effects of fabrication routes and material parameters on the control of superconducting currents by gate voltage
Leon Ruf, Tosson Elalaily, Claudio Puglia +12
The control of a superconducting current via the application of a gate voltage has been recently demonstrated in a variety of superconducting devices. Although the mechanism underl…
Half-integer Shapiro steps in highly transmissive InSb nanoflag Josephson junctions
Andrea Iorio, Alessandro Crippa, Bianca Turini +8
We investigate a ballistic InSb nanoflag-based Josephson junction with Nb superconducting contacts. The high transparency of the superconductor-semiconductor interfaces enables the…
Gate control of superconducting current: Mechanisms, parameters and technological potential
Leon Ruf, Claudio Puglia, Tosson Elalaily +14
In conventional metal-oxide semiconductor (CMOS) electronics, the logic state of a device is set by a gate voltage (VG). The superconducting equivalent of such effect had remained…
Josephson Diode Effect in High Mobility InSb Nanoflags
Bianca Turini, Sedighe Salimian, Matteo Carrega +6
We report evidence of non-reciprocal dissipation-less transport in single ballistic InSb nanoflag Josephson junctions, owing to a strong spin-orbit coupling. Applying an in-plane m…
Evidence of Josephson coupling in a few-layer black phosphorus planar Josephson junction
Francesca Telesio, Matteo Carrega, Giulio Cappelli +7
Setting up strong Josephson coupling in van der Waals materials in close proximity to superconductors offers several opportunities both to inspect fundamental physics and to develo…
Photonic heat rectification in a coupled qubits system
Andrea Iorio, Elia Strambini, Géraldine Haack +2
We theoretically investigate a quantum heat diode based on two interacting flux qubits coupled to two heat baths. Rectification of heat currents is achieved by asymmetrically coupl…
rf-SQUID measurements of anomalous Josephson effect
Claudio Guarcello, Roberta Citro, Ofelia Durante +6
We discuss the response of an rf-SQUID formed by anomalous Josephson junctions embedded in a superconducting ring with a non-negligible inductance. We demonstrate that a properly s…
Investigation of InAs based devices for topological applications
Matteo Carrega, Stefano Guiducci, Andrea Iorio +10
Hybrid superconductor/semiconductor devices constitute a powerful platform to investigate the emergence of new topological state of matter. Among all possible semiconductor materia…
Vectorial control of the spin-orbit interaction in suspended InAs nanowires
Andrea Iorio, Mirko Rocci, Lennart Bours +6
Semiconductor nanowires featuring strong spin-orbit interactions (SOI), represent a promising platform for a broad range of novel technologies, such as spintronic applications or t…
