Samenvatting

A practical CV-QKD system has been presented and characterized. Our real-time GPU- based receiver (Bob) implementation demonstrates effective calibration, digital signal processing, and post- processing techniques. The system achieves peak finite-size secret key rates up to 5.8 Mbps over 12.8 km and 0.5 Mbps over a 25.7 km fiber distance. Additionally, we conducted a numerical simulation analysis to enhance the system’s resilience to quantum channel loss. Various scenarios were explored, focusing on potential improvements in excess noise, reconciliation efficiency, and quantum efficiency, aiming to extend distance tolerances beyond 50 km
