Tinggui Zhang, Bobo Hua, Ming Li, Ming-Jing Zhao, Hong Yang

摘要:

研究了一类量子态在二体和多体情况下的局域幺正等价性。给出了充分必要条件。作为特例,给出了各向同性态和werner态的局域么正等价类。然后研究了这类量子态的局域幺正相似等价性,分析了局域幺正相似等价的充要条件。

英文摘要:

We consider the local unitary equivalence of a class of quantum states in bipartite case and multipartite case. The necessary and sufficient condition is presented. As special cases, the local unitary equivalent classes of isotropic state and werner state are provided. Then we study the local unitary similar equivalence of this class of quantum states and analyze the necessary and sufficient condition.
