摘要：
The parameters for the evaluation of quantum telepotrtation efficiency schemes for continuous variables were discussed. The status of the local or remote operations to be performed on the input state was summarized by the use of quantum entanglement. The difference between quantum duplication and classical measurement depicted the teleported state with fidelity value larger than 2/3, to be the best possible remaining copy of the input state.
