Highlights:
- Analyzes two models for CV-QKD block size requirements under composable security constraints.
- Investigates quantum-classical channel coexistence in a flexible-grid optical network: finds minimum channel spacing (≈112.5 GHz or 125 GHz depending on total power) for 8×200 G transceivers and up to ~15 km link distance.
- Discusses the role of SDN-enabled network management in dynamically allocating quantum channels, enabling seamless integration of CV-QKD with classical networks.
