Fiber Entanglement Distribution, and Quantum-Classical Coexistence in C Band
Bhaskar Kanseri, Nishant Kumar Pathak, Abhay Singh Dulta · 2025
We experimentally demonstrate polarization-entangled photon distribution over 50km telecom fiber, achieving robust Bell violation and secure QKD with copropagation of classical data at C-band, enabling cost-effective quantum networks using existing telecom infrastructure.
