论文摘要
在本文中，我们基于两个两部分纠缠的挤压状态研究了量子不一致和同意的量子不一致和同意的行为。最大纠缠的挤压状态被认为是一个完美的国家，而非最大的纠缠挤压状态被称为准妻子状态。我们表明，对于这两种状态，量子相关性的行为保持不变。但是，量子相关量在完美的状态中的含量非常高于准妻子中的量子。此外，我们表明，对于挤压参数的大量值，准妻子状态在定性和定量上接近完美的妻子状态。
In this paper, we investigate comparatively the behaviors of quantum discord and concurrence for Werner states based on two bipartite entangled squeezed states. The maximally entangled squeezed states are regarded as a perfect-Werner states, while the non-maximally entangled squeezed states are called quasi-Werner states. We show that, the behavior of the quantum correlations keep unchanged for these two types of states. However, the quantum correlations amount presents in perfect-Werner states is very higher than that presents in quasi-Werner ones. Furthermore, we show that for large values of squeezed parameter the quasi-Werner states approaches the perfect-Werner states qualitatively and quantitatively.
