In this paper we study quantum correlation (QC) swapping between two different kinds of quantum-correlated states. To be concrete, one is the famous Werner state while another is a kind of separable state. We employ measurement-induced disturbance (Luo 2008 Phys. Rev. A 77 02230) as the quantifier to characterize and quantify QC. We work out QCs in all the concerned states and concretely analyze their behaviors and properties such monotony features and thresholds. We find that a long-distance shared QC can be generated from two short-distance ones via intermediate measure. Moreover, the amount of the long-distance shared QC cannot reach that in the Werner state but that in the separable state.

在本文中，我们研究了两种不同类型的量子相关状态之间的量子相关（QC）交换。具体来说，一个是著名的维尔纳州，另一个是一种可分离的州。我们采用测量引起的干扰（Luo 2008 Phys。Rev. A 77 02230）作为量化器来表征和量化QC。我们在所有相关州制定了质量控制，并具体分析了它们的行为和特性，例如单调特征和阈值。我们发现可以通过中间度量从两个短距离的QC生成长距离的共享QC。而且，长距离共享QC的量不能达到在Werner状态下的数量，而不能达到在可分离状态下的数量。
