Chen Yin-Hua, Deng-Yu Zhang, Feng Gao, Zhan Xiao-Gui · Chinese Physics Letters · 2009
We propose a protocol of remote information concentration achieved by a four-particle cluster state. To achieve the task, Bell state measurement and unitary operation are needed. The result shows a peculiar phenomenon that the remote information concentration is not always successful but with certain probability.
