Dynamic Rerouting of Quantum Key Distribution Links During Live Operation for Software-Defined Networks
Live rerouting of quantum key distribution links poses new synchronization challenges. We demonstrate the seamless handling of multi-minute channel interruptions and fiber length changes exceeding 100 km during live system operation and over deployed fiber, using free-running low-cost quartz oscillators and without a dedicated clock channel. ©2025 The Author(s)
