中文摘要：

通过研究具有DM（Dzyaloshinski-Moriya）各向异性自旋轨道相互作用的两自旋量子比特模型,分别从初态为纯态和混合态的角度分析了几何相位与纠缠度随时间演化特性之间的关联,并得到参数D的选取会影响到几何相位和纠缠度随时间的演化特性,D取值越大变化越缓慢.

英文摘要：

The geometric phase and the entanglement of two-qubit quantum system with Dzyaloshinski- Moriya （DM） anisotropic interaction are calculated. For pure or mixed initial states, the characteristic of time evolution of geometric phase and entanglement are analyzed respectively,and the fine corresponding relations are found. In addition,we also find the value of parameter D could influence on the characteristic of time evolution of geometric phase and the entanglement, the evolution becomes slow when the value of parameter D is greater.
