Nonlocal quantum entanglement is a fundamental resource for future networks. However, the efficiency of generating nonlocal between distant nodes severely limited by exponential loss incurred when locally generated entangled states are distributed through lossy channels. This limitation becomes more pronounced in practical scenarios requiring simultaneous distribution multiple pairs. While classical multiplexing approaches, such as spatial, temporal, and frequency multiplexing, can increase generation rate, they do not improve single-shot transmission efficiency. In contrast, enabled high-dimensional encoding single photons, allows parallel pairs round, thereby enhancing overall generation. Quantum thus offers promising route toward scalable review introduces mechanisms using multiplexing. It focuses on two main approaches single-photon biphoton distribution, respectively. then examines how accelerate logical entanglement. Finally, it briefly explores potential building large-scale
