Entanglement-Based Artificial Topology: Neighboring Remote Network Nodes
To address the limitations of fixed physical topologies and restricted inter-network connectivity in quantum local area networks (QLANs), this paper proposes a dynamic network-layer topology reconfiguration method based on multipartite entanglement. By designing distributable multipartite entangled states and integrating local quantum operations with a novel entanglement routing protocol, the approach enables on-demand construction of “artificial topologies” and “artificial neighborhoods” across QLANs—overcoming functional bottlenecks inherent to bipartite entanglement in inter-network linking. This work constitutes the first systematic application of multipartite entanglement to quantum network topology engineering, supporting real-time, traffic-driven reconfiguration of artificial network structures. Experimental validation demonstrates significant improvements in logical connectivity between remote nodes, network flexibility, and entanglement resource utilization. The method establishes a new paradigm for scalable and engineerable quantum internet architectures.
