Giant nonlinearity of kinetic inductance in superconducting hybrid strip
D. Yu. Vodolazov, Yu. P. Korneeva, M. A. Dryazgov +6
We demonstrate giant nonlinearity of the kinetic inductance in a superconducting NbN/Al hybrid strip. In contrast to ordinary superconductors, where the maximum observed curr…
Superconducting properties of NbSc film deposited by magnetron co-sputtering
Paul Berezhnoy, Anna Elistratova, Zakhar Enbaev +8
The technology has been developed for synthesizing NbSc films using magnetron co-sputtering from Nb and Sc targets. The material synthesis was accompanied by structural…
Practical way to increase nonlinearity of kinetic inductance of superconductor
Yu. P. Korneeva, M. A. Dryazgov, I. V. Trofimov +7
This work demonstrates that depositing a thin layer of Mo (5-15 nm) onto a 10 nm thick NbN strip leads to a significant increase in the nonlinearity of the kinetic inductance …
Resource-efficient low-loss four-channel active demultiplexer for single photons
M. Dryazov, Yu. Biriukov, I. Dyakonov +12
We report a design and implementation of a resource-efficient spatial demultiplexer which produces 4 indistinguishable photons with efficiency of 39.7% per channel. Our scheme is b…
