Bolometer operating at the threshold for circuit quantum electrodynamics
R. Kokkoniemi, J. -P. Girard, D. Hazra +7
Radiation sensors based on the heating effect of the absorbed radiation are typically relatively simple to operate and flexible in terms of the input frequency. Consequently, they…
Optimized heat transfer at exceptional points in quantum circuits
Matti Partanen, Jan Goetz, Kuan Yen Tan +12
Superconducting quantum circuits are potential candidates to realize a large-scale quantum computer. The envisioned large density of integrated components, however, requires a prop…
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…
