We investigate the storage and retrieval of photon entanglement based on electromagnetically induced transparency where atomic thermal motion cannot be neglected. The reversible transfer of entanglement between atomic ensembles and photon modes is described in terms of the dark state generalized to a mixture of entangled collective moving atoms and entangled photon modes. We analyze the retrieval ability of photon entanglement from atomic ensembles with inhomogeneous broadening and find that the scheme in the degenerated and resonant light–atom configuration is almost immune to atomic thermal motion.
