Abstract: Quantum Relay-Assisted Free-Space Optical Communication System under Atmospheric Turbulence. The present invention relates to a relay-assisted quantum free- space optical communication system for transmission of quantum optical signals through atmospheric propagation channels affected by turbulence, pointing errors, and additive Gaussian detection 5 noise. The system comprises a transmitter node configured for classical-to-quantum conversion and coherent-state encoding, a first atmospheric communication channel, a decode-and-forward relay node configured for signal decoding, regeneration, and retransmission, a second atmospheric communication channel, and a receiver node configured for quantum signal detection and measurement. Atmospheric turbulence is characterized using a doubly inverted 10 gamma-gamma turbulence model. The relay-assisted segmented transmission architecture reduces effective atmospheric propagation impairment and improves communication reliability under practical atmospheric communication conditions.
