摘要：

In this paper, we explore the channel capacity of the 4-qubit 4-term cluster state (i. e. (vertical bar 0000 > + vertical bar 0011 > + vertical bar 1100 > - vertical bar 1111 >)/2) for splitting arbitrary two-qubit quantum information. After our extensive investigations, we found that 4 out of 12 possible distributions of the 4 qubits can be utilized to realize bipartite splitting. In terms of each distribution, the corresponding splitting scheme is presented and LOCCs (local operation and classical communication) are explicitly given.
