我们通过利用高阶奇异值分解技术和态的局域对称性，提出了一种在局域幺正等价下针对任意维度的一般多体纯态的实用纠缠分类方案。借助该方案，克劳斯提出的确定n - 量子比特态局域幺正等价的方法被扩展到了任意维度多体态的情形。
We propose a practical entanglement classification scheme for general multipartite pure states in arbitrary dimensions under local unitary equivalence by exploiting the high order singular value decomposition technique and local symmetries of the states. By virtue of this scheme, the method of determining the local unitary equivalence of n-qubit states proposed by Kraus is extended to the case for arbitrary dimensional multipartite states.
