Teleportation of a two-atom entangled state using a single EPR pair in cavity QED

We propose a scheme for teleporting a two-atom entangled state incavity quantum electrodynamics (QED). In the scheme, we choose asingle Einstein--Podolsky--Rosen (EPR) pair as the quantum channel whichis shared by the sender and the receiver. By using the atom--cavity-fieldinteraction and introducing an additional atom, we can teleportthe two-atom entangled state successfully with a probability of 1.0.Moreover, we show that the scheme is insensitive to cavity decayand thermal field.
