An alternative scheme is proposed for teleportation of an unknownatomic-entangled state. The scheme is based on the resonant interaction of atwo-mode cavity field with a Λ-type three-level atom. In contrastwith the previously proposed scheme of [Commun. Theor. Phys. 47 (2007) 253], the present scheme is ascendant, since the fidelity is 1.0 in principlesimilarly without the Bell-state measurement. The scheme may be generalized to not only the teleportation of the cavity-mode-entangled-state but alsothe teleportation of the multi-atomic entangled states included ingeneralized GHZ states. And the scheme is experimentally feasible based onthe current cavity QED technique. |
