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