Abstract:
Quantum wireless multi-hop networks are a fundamental component of the global quantum communication infrastructure. However, existing quantum communication protocols are constrained by limitations in capacity and efficiency, primarily due to their reliance on a single degree of freedom for encoding quantum information. In contrast, the protocol presented in this study leverages hyperentangled Bell states across both polarization and spatial-mode degrees of freedom, thereby overcoming these limitations. Compared to traditional approaches that employ bipartite entanglement within a single polarization degree of freedom, the proposed protocol significantly enhances the communication capacity. This innovative approach not only improves the overall efficiency of quantum communication but also contributes to the scalability of quantum multi-hop networks, offering a promising solution to the challenges encountered by current quantum communication protocols.
