Entanglement diversion and quantum teleportation of entangled coherent states

The proposals on entanglement diversion and quantum teleportation ofentangled coherent states are presented.In these proposals, the entanglement between two coherent states,alpharangle and $|-alpharangle$, with the same amplitude but a phase differenceof $pi$ is utilized as a quantum channel. The processes of the entanglement diversion and the teleportation are achieved by using the 50/50 symmetric beam splitters, the phase shifters and the photodetectors with the help of classical information.
