利用单个可移动电子实现电子纠缠的有效集中
Efficient electronic entanglement concentration assisted with single mobile electron
摘要：
我们提出了一个有效的纠缠浓度协议（ECP）的移动电子与电荷检测。该方案与其他ECP方案不同，它可以从一对纠缠度较小的态和一个移动电子以一定的概率得到一个最大纠缠对。在电荷检测的帮助下，它可以重复以达到更高的成功概率。它也不需要知道原始的少纠缠态的系数。所有这些优点使得该协议在当前的分布式量子信息处理中非常有用。
英文摘要：
We present an efficient entanglement concentration protocol (ECP) for mobile electrons with charge detection. This protocol is quite different from other ECPs for one can obtain a maximally entangled pair from a pair of less-entangled state and a single mobile electron with a certain probability. With the help of charge detection, it can be repeated to reach a higher success probability. It also does not need to know the coefficient of the original less-entangled states. All these advantages may make this protocol useful in current distributed quantum information processing.
