Abstract
This paper presents a novel quantum key distribution (QKD) protocol designed specifically for scalable photonic networks. The protocol leverages the inherent advantages of a multi-hop, all-topological architecture to overcome the limitations of traditional QKD systems regarding key transmission distance and rate. We propose a scheme utilizing quantum entanglement and state transformations within the network to facilitate distributed key generation and secure key distribution. The core innovation lies in the network topology itself, which allows for robust error correction and eavesdropping detection, ultimately leading to a highly secure and high-throughput quantum communication system. The theoretical analysis demonstrates the protocol's resilience to various attack scenarios and highlights its potential for practical implementation in large-scale quantum networks.
