High-resistivity niobium nitride films for unity-efficiency SMSPDs at telecom wavelengths and beyond
Philipp Zolotov, Sergey Svyatodukh, Alexander Divochiy +2
The sensitive element of superconducting single-photon detectors made in the form of a microstrip promise to resolve significant limitations caused by their typical design. However…
A countermeasure against bright-light attack on superconducting nanowire single-photon detector in quantum key distribution
Mikhail Elezov, Roman Ozhegov, Gregory Goltsman +1
We present an active anti-latching system for superconducting nanowire single-photon detectors. We experimentally test it against a bright-light attack, previously used to compromi…
Spectrally resolved single-photon imaging with hybrid superconducting - nanophotonic circuits
O. Kahl, S. Ferrari, V. Kovalyuk +6
The detection of individual photons is an inherently binary mechanism, revealing either their absence or presence while concealing their spectral information. For multi-color imagi…
Potential of a Superconducting Photon Counter for Heterodyne Detection at Telecommunication Wavelength
Mikhail Shcherbatenko, Yury Lobanov, Alexander Semenov +6
Here, we report on successful operation of a NbN thin film superconducting nanowire single-photon detector (SNSPD) in a coherent mode (as a mixer) at the telecommunication waveleng…
Non-bolometric bottleneck in electron-phonon relaxation in ultra-thin WSi film
M. Sidorova, A. Kozorezov, A. Semenov +6
We developed the model of the internal phonon bottleneck to describe the energy exchange between the acoustically soft ultrathin metal film and acoustically rigid substrate. Discri…
Sensitivity of a superconducting nanowire detector for single ions at low energy
M. Sclafani, M. Marksteiner, F. McLennar Keir +5
We report on the characterization of a superconducting nanowire detector for ions at low kinetic energies. We measure the absolute single particle detection efficiency and trac…
