Inter-Campus Converged Fiber/Free-Space C-Band QKD Link During Daylight
We demonstrate a practical inter-campus Quantum Key Distribution (QKD) implementation utilizing C-band time-bin/phase encoding over a converged 750 m urban Free-Space Optical (FSO) and fiber link. To address the challenges of real-world deployment, the system was operated during daylight hours and evaluated in a coexis...
