Xiaofeng Yin, Yimin Liu, Zhang Wen, Zhanjun Zhang · Communications in Theoretical Physics · 2010
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 QI sender and receivers for tri-splitting or bi-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.
