We study the entanglement of the para-Bose entangled coherent states by adopting the entanglement of formation and propose a scheme of probabilistic teleportation via para-Bose entangled coherent states. It is found that the mean fidelity of the scheme increases with the decrease of the para-Bose parameter h 0 in the case of non-maximally entangled para-Bose entangled coherent states.

We study the entanglement of entangled coherent states in vacuum environment by employing the entanglement of formation and propose a scheme to probabilistically teleport a coherent superposition state via entangled coherent states, in which the amount of classical information sent by Alice is restricted to one bit. The influence of decoherence due to photon absorpation is considered. It is shown that decoherence can improve the mean fidelity of probabilistic teleportation in some situations.

We introduce photon-added entangled coherent states (unnormalized) : and investigate the entanglement by employing the entropy of entanglement. Then, we propose a scheme of probabilistic teleportation via photon-added entangled coherent states. It is shown that the mean fidelity of the scheme can be increased by exciting entangled coherent states in the case of nonmaximally entangled quantum channel. The violation of the Clauser?Horne?Shimony?Holt inequality for photon-added entangled coherent states is also examined.
