计算纠缠多面体

Computing Entanglement Polytopes

Konstantin Wernli

摘要:

在arXiv:1208.0365中,引入纠缠多面体作为多体纠缠的SLOCC分类的粗化。用纠缠多面体对纠缠进行分类的优点是对所有维度都有一个有限的层次,并且一些参数在系统大小上是线性的。在arXiv:1208.0365中,提出了一种使用几何不变理论计算纠缠多面体的方法。在这篇论文中,我们考虑其他方法来计算它们。一些几何和代数的工具,可以用来计算不等式给出的纠缠多面体的外部近似。此外,我们提出了一种数值方法,在理论上,可以计算任何给定的SLOCC类的纠缠多面体给定的代表。利用它对$2 \times 3 \times N$系统的纠缠多面体进行了分类。

英文摘要:

In arXiv:1208.0365 entanglement polytopes where introduced as a coarsening of the SLOCC classification of multipartite entanglement. The advantages of classifying entanglement by entanglement polytopes are a finite hierarchy for all dimensions and a number of parameters linear in system size. In arXiv:1208.0365 a method to compute entanglement polytopes using geometric invariant theory is presented. In this thesis we consider alternative methods to compute them. Some geometrical and algebraical tools are presented that can be used to compute inequalities giving an outer approximation of the entanglement polytopes. Furthermore we present a numerical method which, in theory, can compute the entanglement polytope of any given SLOCC class given a representative. Using it we classify the entanglement polytopes of $2 \times 3 \times N$ systems.
