A scheme is presented for realizing long-distance quantum communication with individual atoms and atomic ensembles. In the scheme, deterministic and storable atom-photon entanglement sources can be obtained by adiabatic evolution of dark states, which makes this scheme largely enhance the efficiency for long-distance entanglement distribution. Furthermore, due to many-atom interference effect, requirement of the strong-coupling condition can be greatly relaxed. Thus this scheme opens an alternate avenue for a scalable quantum network.
