Abstract |
We present our recent achievements in the development of superconducting nanowire single-photon detectors (SNSPDs) integrated with optical waveguides on a chip. We demonstrate both single-photon counting with up to 90% on-chip-quantum-efficiency (OCDE), and the heterodyne mixing with a close to the quantum limit sensitivity at the telecommunication wavelength using single device. |

Abstract |
В третий том книги «Программирование: введение в профессию» вошли части V–VIII. В части V рассматриваются системные вызовы для ввода-вывода, управление процессами, механизмы взаимодействия процессов, такие как сигналы и каналы, а также понятие терминала и связанные с ним явления, в том числе сеансы и группы процессов, виртуальные терминалы, управление дисциплиной линии. Часть VI посвящена компьютерным сетям; даётся небольшой обзор протоколов, используемых в сети Интернет, рассмотрена подсистема сокетов и событийно-ориентированное построение серверных программ. В части VII рассматриваются вопросы, связанные с разделяемыми данными, критические секции, взаимоисключение; даются базовые сведения о библиотеке pthread. Часть VIII содержит ряд сведений о внутреннем устройстве операционной системы; в частности, рассматриваются различные модели виртуальной памяти, подсистема ввода-вывода и т.п. |

Abstract |
Recently bright-light control of the SSPD has been demonstrated. This attack employed a “backdoor” in the detector biasing scheme. Under bright-light illumination, SSPD becomes resistive and remains “latched” in the resistive state even when the light is switched off. While the SSPD is latched, Eve can simulate SSPD single-photon response by sending strong light pulses, thus deceiving Bob. We developed the experimental setup for investigation of a dependence on latching threshold of SSPD on optical pulse length and peak power. By knowing latching threshold it is possible to understand essential requirements for development countermeasures against blinding attack on quantum key distribution system with SSPDs. |

Abstract |
This document provides supplementary information to “Spectrally multiplexed single-photon detection with hybrid superconducting nanophotonic circuits", DOI:10.1364/optica.4.000557. Here we detail the on-chip spectrometer design, its characterization and the experimental setup we used. In addition, we present a detailed report concerning the characterization of the superconducting nanowire single photon detectors. In the final sections, we describe sample preparation and characterization of the nanodiamonds containing silicon vacancy color centers. |
