This research examines the impact of predictive adaptive optics control on secret key rates in LEO QKD downlinks. It demonstrates how traditional integral control fails during rapid satellite passes and turbulent conditions, leading to signal fades. The implementation of predictive control strategies stabilizes the optical channel to minimize errors and maximize throughput for secure communications.
