| 摘 要： | 对三体纯态,V.Coffman等提出了分布纠缠的概念及纠缠的度量"tangle".本文由变换算符出发,以三粒子作为量子通道对一个任意的粒子态实现控制隐形传送为例,给出纠缠度与量子控制隐形传态之间满足的关系.

| Abstract: | For pure three-qubit states,V.Coffman et.al put forward a concept of distributed entanglement and a measure of entanglement called "tangle".In this paper we have derived the formula from the transformation operators.The relation of controlled quantum teleportation with entanglement measure is discussed. |
