Abstract
In article number 2400149, Arindam Dutta and co-workers study the implementation of high-dimensional quantum key distribution protocols, HD-Ext-B92 and HD-BB84, via satellite. The study modifies key rate calculations to explore variations in key rate, probability distribution, and quantum bit error rate (QBER) with respect to dimension and noise. The research examines how the average key rate changes with zenith angle and link length under different weather conditions, showing HD-BB84's superior performance in higher dimensions despite higher QBER saturation. The down-link configuration is shown to be preferable over the up-link configuration.
