Abstract  This paper proposes a scheme for entanglement swapping based on cavity QED. The two atoms to be entanglement-swapped can be separated over long distance. The scheme is a non-post-selection one with the success probability of 1/2.
Keywords:  entanglement      entanglement swapping      cavity QED
