纠缠基与正交完备基的一般结构

Entanglement bases and general structures of orthogonal complete bases

Zai-Zhe Zhong

摘要:

在量子力学和量子信息中,建立正交基是一种有用的手段。不可扩展乘积基的存在促使我们研究纠缠基问题。定义了纠缠基和精确纠缠基的概念,给出了精确纠缠基的一个定理。讨论了正交完备基的一般结构。给出了两个应用实例。最后讨论了一般结构形式的转换问题。

英文摘要:

In quantum mechanics and quantum information, to establish the orthogonal bases is a useful means. The existence of unextendible product bases impels us to study the `entanglement bases' problems. In this paper, the concepts of entanglement bases and exact-entanglement bases are defined, and a theorem about exact-entanglement bases is given. We discuss the general structures of the orthogonal complete bases. Two examples of applications are given. At last, we discuss the problem of transformation of the general structure forms.
