Title

"Quantum Approaches to Time Synchronization and Network Services"

Abstract

Time synchronization is a fundamental requirement for modern communication networks, supporting applications such as localization, distributed control, edge services, and secure communications. However, classical synchronization methods face important limitations due to delay asymmetry, jitter, clock drift, and other network-induced uncertainties. In this talk, I will discuss how quantum technologies can enable more precise and robust synchronisation, with a focus on entanglement-based approaches such as time-correlated photons and Hong–Ou–Mandel interference. I will then show how the same quantum toolbox can extend beyond synchronization to support other important network functionalities, including secure timing, quantum-enhanced positioning, and future communication services. I will also briefly highlight how quantum methods may support network optimization and control, for example, through quantum-enhanced software-defined networking, where quantum algorithms could help address complex routing and resource-management problems in future 6G communication systems. Overall, the talk aims to show how quantum technologies can evolve from physical-layer advances into broader enablers for next-generation communication networks.
