The study employed Rayleigh and Hoyt statistical models to derive expressions for error probability, quantum bit error rate, and secret key generation rate. Key findings reveal that larger beam waist increases errors and reduces secure key rates, receiver aperture improvements plateau beyond certain thresholds, and asymmetric pointing errors can surprisingly outperform symmetric misalignment in some scenarios. ## Full article daily.dev links to this article rather than hosting it.
