Research Study on Quantum Key Distribution in Quantum Communication

Abstract

This research paper explores the integration of Quantum Key Distribution (QKD) networks with Telecommunication Networking technology to enhance the security of communication. QKD, leveraging the principles of quantum physics, offers secure key exchange between users, detecting any potential eavesdropping during communication. Traditionally limited to point-to-point connections, the paper addresses the need for a unified control plane for efficient resource allocation in QKD networks. It discusses the challenges of multi-resource allocation, secret-key management, and survivability, offering potential solutions. The paper details recent progress in QKD networks and presents three practical cases illustrating the benefits of combining QKD with SDN. The paper concludes by summarizing the findings and emphasizing the significance of QKD networks in developing secure multi-user communication scenarios in the evolving landscape of information networks.
