Controlled Remote State Preparation
Zhang-Yin Wang, Yimin Liu, Zuo Xue-Qin, Zhanjun Zhang · Communications in Theoretical Physics · 2009
We present a scheme for remotely preparing a state via the controls of many agents in a network. In the scheme, the agents' controls are achieved by utilizing quantum key distribution. Generally, the original state can be restored by the receiver with probability 1/2 if all the agents collaborate. However, for certain type of original states the restoration probability is unit.
