"Duan-Lukin-Cirac-Zoller (DLCZ)-based multimode quantum networks rely on efficient spatial-to-fiber coupling, yet environmental perturbations compromise this performance. We develop a cascaded adaptive feedback control system integrated into the quantum entanglement source preparation path. Leveraging a power-feedback hill-climbing algorithm, it dynamically regulates piezoelectric-actuated mirrors to achieve autonomous multi-dimensional beam alignment. Experiments show it rapidly boosts single-mode fiber (SMF) coupling efficiency from 0.39% to 70.74% within 75 seconds. Importantly, it enhances the stability of the atom-photon interface\u2014critical for quantum light-matter interactions\u2014providing a practical framework for efficient, robust spatial light transmission in scalable quantum networks."
