Probabilistic teleportation of unknown atomic state using W class states

In this paper, we propose two physical schemes, which can teleport unknown atomic state from user A (Alice) to user B (Bob) using the W class state as quantum channel. The two schemes are all based on Cavity QED techniques. The fidelity of the teleported state in the two schemes is equal to 1.0, and the successful probability of the schemes is decided by the smaller superposition coefficient of the state used as quantum channel. Each of the schemes has its own advantages.
