Flexible Strategies and Practical Guidelines Toward the Integration of Quantum and Classical Optical Communications

Year: 2026

Type: conference-paper

Abstract: This invited article analyzes flexible integration and coexistence strategies enabling quantum channels to operate alongside classical channels, adopting continuous variable quantum key distribution (CV-QKD), as a practical approach to quantum-secure communication in future high-capacity optical networks.Spectral engineering techniques and wavelength flexible operation are discussed, highlighting their relevance for different optical network scenarios. We report our recent results, providing practical guidelines and outlining how flexibility can support the evolution of integrated quantum-classical communications in future optical infrastructures.
