Entanglement and nonlocality of photon-added entangled coherent states and quantum probabilistic teleportation
Jian-Song Zhang, Jing‐Bo Xu · Physica Scripta · 2009
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.
