论文摘要
自我互动和与环境的互动倾向于将量子系统推向最大纠缠状态。这是对破坏的定义。我们认为,这些最大的纠缠状态属于明确定义的类别,这些阶级可以由某些纠缠不变的值唯一描述。在讨论了这些想法之后,我们介绍了许多通用系统的最大纠缠状态的示例,在三方系统的最纠缠的类中构建紧凑型状态,并建议如何为其他$ n $ partite Systems构建它们。我们研究纠缠班级的随机步行,以查看矫正性如何在实践中起作用。
Self-interactions and interaction with the environment tend to push quantum systems toward states of maximal entanglement. This is a definition of decoherence. We argue that these maximally entangled states fall into the well-defined classes that can be uniquely described by the values of certain entanglement invariants. After discussing these ideas we present examples of maximally entangled states for a number of generic systems, construct compact states in the most entangled classes for tripartite systems, and suggest how they may be constructed for other $n$-partite systems. We study random walks through the space of entanglement classes to see how decoherence might work in practice.
