Non-classicality versus channel capacity for a superposition of entangled coherent states

The entropy and Mandel function as entanglement predictable of multipartite entangled coherent states are studied. The possibility of using these states as quantum channel to perform quantum teleportation is investigated. Quantum teleportation is achieved by using both even and odd entangled coherent states in the presence of environmental noise. The effect of the field’s parameters are investigated on the fidelity of the teleported state.
