摘要
给出了三粒子系统三类解纠缠的定义 ,研究了三粒子系统纯态解纠缠的三个基本规律 ,发现存在一些可以解纠缠为直积态集或“一粒子直积 两粒子分离”态集或完全分离态集的三粒子纠缠态集 ,但一个普适的将三粒子纠缠态集解纠缠为直积态集或“一粒子直积 两粒子分离”态集或完全分离态集的装置均不存在 .
Three kinds of definitions of disentanglement of 3-particle systems are given. Three basic regulations of a 3-particle system pure-state disentanglement are completely analyzed. It is shown that there are some sets of 3-particle entangled states that can be disentangled into product states or 1-particle product and 2-particle separable states or fully separable states, but a universal disentangling machine into product states or 1-particle product and 2-particle separable states or fully separable states cannot exist.
