  Title Development of the experimental setup for investigation of latching of superconducting single-photon detector caused by blinding attack on the quantum key distribution system Type Conference Article
  Year 2017 Publication EPJ Web Conf. Abbreviated Journal EPJ Web Conf.  
  Volume 132 Issue Pages 01004 (1 to 2)  
  Keywords QKD, SSPD, SNSPD  
  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.

  Title Long-distance fiber-optic quantum key distribution using superconducting detectors Type Conference Article
  Year 2015 Publication Proc. Optoelectron. Instrum. Abbreviated Journal Proc. Optoelectron. Instrum.  
  Volume 51 Issue 6 Pages 548-552  
  Keywords QKD, SSPD, SNSPD  
  Abstract This paper presents the results of experimental studies on quantum key distribution in optical fiber using superconducting detectors. Key generation was obtained on an experimental setup based on a self-compensation optical circuit with an optical fiber length of 101.1 km. It was first shown that photon polarization encoding can be used for quantum key distribution in optical fiber over a distance in excess of 300 km.
