- Abstract:
- Quantum Key Distribution (QKD) offers secure communication by leveraging core principles of quantum mechanics. Characterization of QKD system is fundamental for comparing the experimental results provided by researchers. Unfortunately, there is no standardized or unified approach; therefore, different researchers present results that provide heterogeneous information, making comparisons difficult. A systematic analysis of the literature is necessary to identify common approaches from a metrological perspective. This paper provides an overview of measurements used to characterize quantum channels, with a focus on parameters such as attenuation, polarization effects, and timing stability. To support this analysis, real-world case studies are examined.
