von Neumann代数的EPR态

EPR states for von Neumann algebras

R. F. Werner

摘要:

在最近的一篇论文[quant-ph/9910066]中,Arens和Varadarajan给出了他们称之为二分复合量子系统的EPR态的特征。根据定义,这样的状态意味着两个子系统中合适的可观测量对之间的完美相关,任务是确定给定状态的所有相关对。在这篇文章中,论证被缩短和简化,同时扩展到一般冯诺依曼代数中的观测量,这自然出现在量子场论中。

英文摘要:

In a recent paper [quant-ph/9910066], Arens and Varadarajan gave a characterization of what they call EPR-states on a bipartite composite quantum system. By definition, such states imply perfect correlation between suitable pairs of observables in the two subsystems, and the task is to determine all such correlated pairs for a given state. In this note the argument is shortened and simplified, and at the same time extended to observables in general von Neumann algebras, which naturally arise in quantum field theory.
