摘要

A protocol is presented for teleporting an unknown arbitrary quantum pure state of a two-state particle from a sender to a distant receiver, via control of multiple players in a network. This protocol operates essentially via a multi-particle entangled state initially shared by the sender, the receiver, and the controlling players in a network. By exploiting this protocol, the success rate of teleportation is 1 and the receiver can restore the original quantum state to be teleported with the help of all controlling players; however, even if one of the controlling players does not cooperate, no information, encoded via amplitude or phase, or both, can be accessed by the receiver.
