Physical-layer Impairment in Integrating QKD to Optical Fiber Networks
Abstract Quantum Key Distribution (QKD) is currently the most mature quantum technology, transitioning from laboratory research to real-world secure communication applications. However, the deployment of dedicated infrastructure for QKD remains prohibitively expensive. A more practical and scalable approach is to integrate QKD with existing optical communication networks, leveraging the current infrastructure to reduce deployment costs. In this […]
