We present a simplified version of a repeater protocol in a cold neutral-atomensemble with Rydberg excitations optimized for two-node entanglementgeneration and describe a protocol for quantum teleportation. Our proposaldraws from previous proposals [Zhao, {\sl et al.}, Phys. Rev. A {\bf 81},052329 (2010)] and [Han, {\sl et al.} Phys. Rev. A {\bf 81}, 052311 (2010)] whodescribed efficient and robust protocols for long-distance entanglement withmany nodes. Using realistic experimental values we predict an entanglementgeneration rate of $\sim$25 Hz and teleportation rate of $\sim$ 5 Hz. Ourpredicted rates match the current state of the art experiments for entanglementgeneration and teleportation between quantum memories. With improvedefficiencies we predict entanglement generation and teleportation rates of$\sim$7.8 kHz and $\sim$3.6 kHz respectively, representing a two order ofmagnitude improvement over the currently realized values. Cold-atom ensembleswith Rydberg excitations are promising candidates for repeater nodes becausecollective effects in the ensemble can be used to deterministically generate along-lived ground state memory which may be efficiently mapped onto adirectionally emitted single photon.
