| Popis: | A maximum entangled atomic system consists of 2-two level atoms interacts locally with their own dissipative cavity, is discussed. We show that, the amount of the survival entanglement of the atomic system decays as the detuning parameter increases or the coupling constant decreases. A theoretical teleportation is suggest to teleport a state of one cavity initially prepared in a superposition coherent state to the second cavity is discussed, by using the atomic system as a channel. It is shown that, the efficiency of the suggested teleportation may be improved by increasing the detuning parameter or decreasing the coupling constant between the atomic systems and the cavities. |
