Light Source Monitoring in Quantum Key Distribution With Single-Photon Detector at Room Temperature

Gan Wang, Zhengyu Li, Yucheng Qiao +3 more

Photon number resolving monitoring is a practical light source monitoring scheme in quantum key distribution (QKD) systems and can, effectively, reduce the risks due to the effects of untrusted sources. This scheme requires a single-photon detector, normally working at low temperature to suppress its dark count rate. In this paper, we use a room-temperature detector and show that the dark count rate is nearly irrelevant to the monitoring performance in our scheme, thus can sufficiently reduce the afterpulsing effect of the detectors as well as relax the requirements on their working conditions and integration complexity, which would be highly desirable for practical high-speed QKD systems with imperfect sources. Furthermore, the influences of parameter drifts at room temperature are analyzed, and the monitoring scheme is testified in a real QKD system.

An efficient performance evaluation modeling tool for SNSPD used in QKD systems

Adil Fadhil Mushatet, Shelan Khasro Tawfeeq

Single-photon detection concept is the most crucial and often difficult factor to determine the performance of quantum key distribution (QKD) systems. One solution to facilitate understanding this concept is to create a virtual environment for modeling, analyzing, and investigating the performance of single photon detectors. In this paper, a simulator for superconducting single photon detectors with time domain visualizer and configurable parameters is presented. The widely used ID281SNSPD in the QKD area was theoretically modeled in terms of pulse analysis, the impact of biasing current and the temperature on the dark counts rate and single photon-detection efficiency and influence of the number of photons per pulse on the single photon-detection efficiency. The simulated results were in good agreement with the theoretical results and the simulator demonstrated its adaptability.

Performance of various quantum-key-distribution systems using 1.55 μm up-conversion single-photon detector

Rongzhen Jiao, Feng Chen-Xu, Ma Hai-Qiang +1 more

The performance of various quantum-key-distribution (QKD) systems is analyzed using 1.55 μm up-conversion single-photon detector. The dependence of quantum efficiency and dark count rate change on the pump power was also discussed. The comparison is based on the secure communication rate as a function of distance for three QKD protocols: the Bennett-Brassard 1984, the Bennett-Brassard-Mermin 1992, and the coherent differential-phase-shift keying protocols. We show that the up-conversion detector allows for higher communication rate and longer communication distance than the commonly used InGaAs/InP APD for all three QKD protocols, and the properties of quantum key distribution system can be greatly improved by this detector.
