纠缠矢量的一个特征

A Characterization For Entangled Vectors

Stan Gudder

摘要:

本文给出了有限维Hilbert空间$H$中纠缠向量的一个简单刻画.该特征是在一个扩展的系数的向量相对于一个正交基$H$。这个简单的充分必要条件包含一个限制,我们还提出了一个更复杂的条件,是完全通用的。虽然这些特征适用于二部系统,我们表明,推广到多部系统也是有效的。

英文摘要:

This article presents a simple characterization for entangled vectors in a finite dimensional Hilbert space $H$. The characterization is in terms of the coefficients of an expansion of the vector relative to an orthonormal basis for $H$. This simple necessary and sufficient condition contains a restriction and we also present a more complicated condition that is completely general. Although these characterizations apply to bipartite systems, we show that generalizations to multipartite systems are also valid.
