局域么正等价下任意多体纠缠态的分类

Classification of Arbitrary Multipartite Entangled States under Local Unitary Equivalence

Jun-Li Li, Cong-Feng Qiao

摘要:

我们提出了一个实用的方法来寻找任意维的多体纠缠态的标准形,无论是纯态还是混合态。通过扩展我们最近的一项工作中发展的技术,构造了混合$N$ -粒子纠缠态的正则形式,它们继承了相应的$N+1$纯态的局域么正对称性.给出了一个系统的表示正则型局域对称性的方案,为验证两个多体纠缠态的局域幺正等价性提供了一种可行的方法.

英文摘要:

We propose a practical method for finding the canonical forms of arbitrary dimensional multipartite entangled states, either pure or mixed. By extending the technique developed in one of our recent works, the canonical forms for the mixed $N$-partite entangled states are constructed where they have inherited local unitary symmetries from their corresponding $N+1$ pure state counterparts. A systematic scheme to express the local symmetries of the canonical form is also presented, which provides a feasible way of verifying the local unitary equivalence for two multipartite entangled states.
