Advancements in Quantum Communication Networks: A Survey

Abstract

Quantum communication networks represent a paradigm shift in secure and efficient data transmission, leveraging the principles of quantum mechanics to enhance security and enable advanced functionalities. This chapter surveys recent advancements in quantum communication networks, focusing on quantum key distribution (QKD), quantum repeaters, and quantum network architectures. The integration of these technologies with existing classical networks is explored, along with challenges in scalability, error correction, and hardware limitations. Future research directions are proposed to address these challenges and pave the way for large-scale quantum networks.
