Schemes for Probabilistic Teleportation of a Three-Atom GHZ Class State via Cavity QED
YI-CAI WANG, Liu Jin-Ming · Communications in Theoretical Physics · 2007
Using a quantum channel composed of a two-atom and a three-atom nonmaximally entangled states, we present two schemes to teleport a three-atom GHZ class state via entanglement swapping in cavity QED with different success probabilities. The schemes can be respectively realized with the large-detuned vacuum cavities and with the large-detuned thermal cavities by separate atomic measurements after we choose appropriate atom-cavity-field interaction time.
