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。
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.
