Teleportation of a Three-atom Entangled W State Using Three EPR Pairs in Cavity QED

We proposed a scheme for teleporting a three-atom entangled W state in cavity QED.In the scheme,three EPR pairs are chosen as quantum channel shared by the sender and the receiver.By using atom-cavity-field interaction and appropriate unitary transformations,the three-atom entangled W state can be teleported successfully with probability 1.0.Moreover,the scheme does not need joint Bell measurement and is insensitive to the cavity decay and thermal field.
