中文摘要：

在这篇论文，我们为由把二个不对称的 W 状态用作量隧道切开一个任意的 2-qubit 量信息建议一个分成三部分的计划。如果二个接受者一起协作，在 schemem，他们装确定的联盟者由执行第一一 4-qubit 恢复量信息集体单一的操作然后二 single-qubit 单一的操作。另外，自从不对称的 W 状态作为量隧道被采用，计划对 decoherence 是柔韧的。

英文摘要：

In this paper we propose a tripartite scheme for splitting an arbitrary 2-qubit quantum information by using two asymmetric W states as the quantum channel. In the schemem if the two recipients collaborate together, they can deterministically recover the quantum information by performing first a 4-qubit collective unitary operation and then two single-qubit unitary operations. In addition, since the asymmetric W states are employed as the quantum channel, the scheme is robust against decoherence.
