Quantum interfaces that generate atom-photon (i.e., spin-wave-photon) entanglement are fundamental building blocks for quantum repeaters. Based on the Duan-Lukin-Cirac-Zoller (DLCZ) protocol in atomic ensembles, atom-photon entanglement can be probabilistically generated. The generation rate of entangled pairs is a core parameter that directly impacts the efficiency of quantum repeaters and quantum communication networks. Recent research on quantum repeaters has shown that temporal, spatial, and spectral multiplexing of quantum memories can effectively improve the entanglement generation rate. In this work, we develop a high-rate scalable six-channel temporal-multiplexed entanglement source via substantially increasing the experimental repetition rate and adopting a scalable pulsed-light fabrication technique. On the one hand, we shorten the experimental cycle to increase the repetition rate by optimizing the response time of the acousto-optic modulator (AOM), precisely controlling the pulse width and interval, and reducing signal transmission delays. Specifically, the AOM response time is reduced to 500 ns, the pulse width to 70 ns, and the pulse interval to 200 ns. On the other hand, we integrate an AOM network with a beam shaping device to realize accurate manipulation of the write pulse train. This structural design improves system compactness, spatial utilization, and stability, facilitating expansion to more time modes. Experimental results demonstrate that compared with conventional single-mode and nonmultiplexed entanglement sources, the generation rates of photon-atom entanglement (entangled photon pairs) are enhanced by factors of 4.42 (4.56) and 5.95 (5.84), respectively. The measured Bell parameter is 2.52, and the storage lifetime reaches 55 μs. The proposed scheme is cost-effective, highly compatible, and easy to operate. On this basis, further operations such as increasing the number of time modes, suppressing background noise, and implementing multimode multiplexing can be carried out. This work provides effective technical pathways and key experimental support for the construction of practical quantum repeaters and large-scale quantum networks.
