Entanglement entropy growth is studied under a form of dynamics that is based on iteration. This approach allows the investigation of the role of decoherence in producing increases of entropy. This has important consequences as far as the study of decoherence is concerned. It is indicated that results are generally independent of Hilbert space partitioning. It is seen that a deep relationship between classical dynamical entropy and the growth of entanglement entropy exists in this kind of model. The former acts to bound the latter and in the asymptotic region, they tend to a common limit.

哈密​​顿动力系统中周期轨道附近的纠缠熵行为

纠缠熵增长是在一种基于迭代的动力学形式下研究的。这种方法允许研究退相干在产生熵增加中的作用。就退相干的研究而言，这具有重要的影响。表明结果通常与希尔伯特空间划分无关。可以看出，在这种模型中，经典动力学熵与纠缠熵的增长之间存在着深刻的关系。前者约束后者，在渐近区域，它们趋向于一个共同的极限。
