摘要
简化 four-qubit 簇状态(即，(| 0000 +| 0011 +| 1100 -| 1111 )/2 ) 为切开一个任意的 single-qubit 量信息(QI ) 被探索。在为切开 tri 的 QI 发送者和接收装置之中的四 qubits 的各种各样的可行分布或切开双性人被发现。当其它简明地被提及时，为分发代表，相应切开计划和他们的 LOCC (本地操作和古典通讯) 充分地被介绍。
The simplified four-qubit cluster state （i.e., （｜0000〉 ＋ ｜0011〉 ＋ ｜1100〉 -｜1111〉）/2） is explored for splitting an arbitrary single-qubit quantum information （QI）. Various feasible distributions of the four qubits among the Q,I sender and receivers for tri-splitting or hi-splitting are found out. For the distribution representations the corresponding splitting schemes and their LOCCs （local operation and classical communication） are presented amply while others are mentioned concisely.
