Abstract: A quantum network is constructed via maximum entangled coherent states. Thepossibility of using this network to achieve communication betweenmulti-participants is investigated. We showed that the probability ofteleported unknown state successfully, depends on the size the used network. Asthe numbers of participants increases, the successful probability does notdepend on the intensity of the field. The problem of implementing quantumteleportation protocol via a noise quantum network is discussed. We show onecan send information perfectly with small values of the field intensity andlarger values of the noise strength. The successful probability of thissuggested protocol increases abruptly for larger values of the noise strengthand gradually for small values. We show that for small size of the used quantumnetwork, the fidelity of the teleported state decreases smoothly, while itdecreases abruptly for larger size of network.
