An Overview on Deployment Strategies for Global Quantum Key Distribution Networks
Jing Wang, Bernardo A. Huberman
Abstract
We present a comprehensive literature review and comparative study on the deployment strategies of quantum key distribution (QKD) networks for global coverage. The state‐of‐the‐art deployment strategies, including terrestrial QKD via optical fibers, free‐space QKD via ground‐based fixed links and ground‐to‐air dynamic links, and satellite QKD, are reviewed and compared in terms of channel loss, interference, distance limit, connection topology, and deployment cost. Selection criteria and deployment strategies are developed to enable a global coverage of QKD networks from intercontinental, long‐haul, metro, to access networks.
