Entanglement diversion and quantum teleportation of entangled coherent states
Cai Xinhua, Guo Jie-Rong, Jianjun Nie, Jia Jin-ping · Chinese Physics · 2006
The proposals on entanglement diversion and quantum teleportation of entangled coherent states are presented. In these proposals, the entanglement between two coherent states, |α and |−α, with the same amplitude but a phase difference of π 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.
