Quantum limited amplification from inelastic Cooper pair tunneling
S. Jebari, F. Blanchet, A. Grimm +7
Nature sets fundamental limits regarding how accurate the amplification of analog signals may be. For instance, a linear amplifier unavoidably adds some noise which amounts to half…

A self-aligned nano-fabrication process for vertical NbN-MgO-NbN Josephson junctions
A. Grimm, S. Jebari, D. Hazra +4
We present a new process for fabricating vertical NbN-MgO-NbN Josephson junctions using self-aligned silicon nitride spacers. It allows for a wide range of junction areas from 0.02…

Multiplying and detecting propagating microwave photons using inelastic Cooper-pair tunneling
Juha Leppäkangas, Michael Marthaler, Dibyendu Hazra +5
The interaction between propagating microwave fields and Cooper-pair tunneling across a DC voltage-biased Josephson junction can be highly nonlinear. We show theoretically that thi…
