摘要：
We consider two independent Jaynes-Cummings models which consist of an atom interacts with electromagnetic field modes. The generation of atom-atom entanglement is investigated. No direct interaction between the two atoms exists. Entanglement can be created using entanglement swapping method by an interference measurement performed on photons. We discuss the influence of off-resonance and the initial state of the atom on the atom-atom entanglement. It is shown that the maximal atom-atom entanglement can be obtained and the atom-atom entanglement is sensitive to the off-resonance and the initial state of the atom.
