| Abstract |
Рассмотрена возможность применения сверхпроводникового нанополоскового детектора, разрешающего число фотонов (Photon-Number Resolving Superconducting Nanowire Photon Detector, PNR-SNPD), в качестве датчика приёмных модулей телекоммуникационных линий. Оценена мощность оптического импульса, необходимая для достижения приемлемо низкой доли ошибочных битов. |

| Abstract |
The use of improved fabrication technology, highly disordered NbN thin films, and intertwined section topology makes it possible to create high-performance photon-number-resolving superconducting single-photon detectors (PNR SSPDs) that are comparable to conventional single-element SSPDs at the telecom range. The developed four-section PNR SSPD has simultaneously an 86±3% system detection efficiency, 35 cps dark count rate, ∼2 ns dead time, and maximum 90 ps jitter. An investigation of the PNR SSPD’s detection efficiency for multiphoton events shows good uniformity across sections. As a result, such a PNR SSPD is a good candidate for retrieving the photon statistics for light sources and quantum key distribution systems. |
