我们提供了使用四部和五部簇态将量子信息分裂成部分的各种方案。说明了单量子比特和双量子比特状态的量子信息分裂（QIS）的显式协议。发现四部簇态可以用于纠缠态的QIS，五部簇态可以用于任意双量子比特态的QIS。这里考虑的方案也是安全的，可以防止某些窃听攻击。
We provide various schemes for the splitting up of quantum information into parts using four- and five-partite cluster states. Explicit protocols for the quantum information splitting (QIS) of single- and two-qubit states are illustrated. It is found that the four-partite cluster state can be used for QIS of an entangled state and the five-partite cluster state can be used for QIS of an arbitrary two-qubit state. The schemes considered here are also secure against certain eavesdropping attacks.
