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 of Conferences Abbreviated Journal EPJ Web of Conferences
Volume 132 Issue 2 Pages (up) 2
Keywords
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.

Volume Issue Pages (up) JTuF2 (1 to 2)
Keywords SSPD, SNSPD
Abstract We fabricate and test superconducting NbN-nanowire single-photon detectors with an integrated optical cavity and anti-reflection coating. We design the cavity and coating such as to maximize absorption in the NbN film of the detector.

Title High-efficiency multi-element superconducting single-photon detector Type Conference Article
Year 2021 Publication Proc. SPIE Abbreviated Journal Proc. SPIE
Volume 11771 Issue Pages (up) 2-8
Keywords PNR SSPD, large active area, detection efficiency
Abstract We present the result of the creation and investigation of the multi-element superconducting single photon detectors, which can recognize the number of photons (up to six) in a short pulse of the radiation at telecommunication wavelengths range. The best receivers coupled with single-mode fiber have the system quantum efficiency of ⁓85%. The receivers have a 100 ps time resolution and a few nanoseconds dead time that allows them to operate at megahertz counting rate. Implementation of the multi-element architecture for creation of the superconducting single photon detectors with increased sensitive area allows to create the high efficiency receivers coupled with multi-mode fibers and with preserving of the all advantages of superconducting photon counters.

Title Single-photon superconducting detectors for practical high-speed quantum cryptography Type Miscellaneous
Year 2001 Publication OFCC/ICQI Abbreviated Journal OFCC/ICQI
Volume Issue Pages (up) Pa3
Keywords NbN SSPD, SNSPD, QKD, quantum cryptography
Abstract We have developed an ultrafast superconducting single-photon detector with negligible dark counting rate. The detector is based on an ultrathin, submicron-wide NbN meander-type stripe and can detect individual photons in the visible to near-infrared wavelength range at a rate of at least 10 Gb/s. The above counting rate allows us to implement the NbN device to unconditionally secret quantum key distRochester, New Yorkribution in a practical, high-speed system using real-time Vernam enciphering.

Keywords superconducting gap; electric fields; femtosecond pulses; near infrared radiation; picosecond pulses; superconductors; thin films
Abstract We studied superconducting gap dynamics in a BCS superconductor NbN and electron doped cuprate superconductor PCCO following excitation with near-infrared (NIR) and narrow band THz pulses. Systematic studies on PCCO imply very selective electron-phonon coupling.
