Comparison of Domestic Single Photon Detectors by QRate With the An-alogues by ID Quantique
Фотоника. 2023. Vol. 17. No. 2. P. 134–145.
The article is devoted to the comparison of specifications of the single photon detectors manufactured by QRate (Russia) and ID Quantique (Switzerland). Their quantum efficiencies, dark count rates, and afterpulse probabilities have been examined in this work. The test results have showed the interchangeability of detectors and noncompliance of foreign detectors with the declared specifications and demonstrated the potential capacities of domestic development.

A 2D model of an InGaAs/InAlAs single-photon avalanche photodiode has been developed. The influence of the active area structure in the multiplication region on the diode’s operating parameters has been studied. It was found that changing the diameter of the structure’s active region leads to a change in the dark current in the linear part ...

A sine-gated single-photon detector (SPD) intended for use in a quantum key distribution (QKD) system is considered in this paper. An “avalanche delay” effect in the sine-gated SPD is revealed. This effect consists in the appearance of an avalanche triggered at the next gate after the photon arrival gate. It has been determined experimentally that ...

In this paper an important parameter of single-photon detectors, such as quantum efficiency, is considered. Errors in determining this parameter lead to significant errors in the parameters of a quantum key distribution system, where such detectors find their application. Three models are proposed to estimate photon detection efficiency or quantum efficiency and their main advantages ...

Abstract— High-resolution photon-counting optical time-domain reflectometry (PC-OTDR) is crucial for the development of fiber-optic sensing and network diagnostics, allowing accurate fault location and long-haul performance optimization. A major step forward for OTDR is reported by combining a superconducting nanowire single-photon detector (SNSPD) with a low-cost FPGA-based time-to-digital converter (TDC) to perform high-resolution measurements over 150 ...

Automated verification of countermeasure against detector-control attack in quantum key distribution
Acheva P., Zaitsev K., Zavodilenko V. V. et al., EPJ QUANTUM TECHNOLOGY 2023 Vol. 10 No. 1 Article 22
Attacks that control single-photon detectors in quantum key distribution using tailored bright illumination are capable of eavesdropping the secret key. Here we report an automated testbench that checks the detector’s vulnerabilities against these attacks. We illustrate its performance by testing a free-running detector that includes a rudimentary countermeasure measuring an average photocurrent. While our testbench ...
