Modulating Retroreflector-Aided UAV-Based FSO/QKD Systems
Duy N. Luong, Duy-Tuan Dao, Cuong T. Nguyen +2
Unmanned aerial vehicles (UAVs)-based free-space optics (FSO)/quantum key distribution (QKD) systems require high-precision pointing mechanisms. This increases system complexity an…
Key Reconciliation with RC-LDPC/Error Estimation for Satellite-based FSO/QKD Systems
Cuong T. Nguyen, Hoang D. Le, Anshul Jaiswal +2
Satellite-based free-space optics (FSO) quantum key distribution (QKD) systems have recently attracted significant research interest due to their potential to enable globally secur…
