Capacity and SKR tradeoff in coexisting classical and CV-QKD metropolitan-reach optical links
Cagla Ozkan, Lucas Alves Zischler, Kadir Gumus +3
We demonstrate power-regime-dependent guardband optimization for quantum-classical coexistence in metropolitan DWDM. Quantum channel at band-edge with 100-150 GHz guardbands achiev…

Accurate and Effective Model for Coexistence of Classical and Quantum Signals In Optical Fibers
Lucas Alves Zischler, Çağla Özkan, Tristan Vosshenrich +10
The rising interest in quantum-level communication has resulted in proposals for coexistence schemes with classical signals within the same fiber optic channel, where the most rece…
