Quantum repeaters are pivotal in the physical layer of quantum internet. For its development, capable efficient entanglement distribution necessary. repeater schemes based on single-photon interference promising due to their potential efficiency. However, involving first-order with photon sources at distant nodes require stringent phase stability components, which poses challenges for long-distance implementation. In this paper, we present a scheme that leverages reduced difficulty stabilization. Additionally, under specific conditions, demonstrate our achieves higher rate between end compared existing schemes. This approach, implementable using only feasible technologies including multimode memories and two-photon sources, offers high rates mild stabilization, leading development repeaters.
