远程制备三粒子纠缠态

Remote Preparation of a Three-paticle Entangled State

在这篇文章中,主要介绍了用三对最大的和非最大两粒子纠缠态作为量子通道远程制备一个三粒子纠缠态的方案。具体方法与量子隐形传态不同的一点就是:我们事先假定Alice已经知道待被制备的态,而Bob并不知道。然后再通过一系列操作得到我们想要制备的态。最后我们得到一个结论:用远程态制备比量子隐形传态更加节省了经典资源。

With three pairs of entangled particles as the quantum channel, we present a scheme for preparing remotely a three-particle entangled state. One different point between remote state preparation and quantum teleportation is that we assume Alice starts with complete classical knowledeg of the state but Bob doesn't. Then the state wanted will be got through a series of operation. Eventually, a conclusion that remote state preparation needs less classical resource than quantum teleportation can be made.
