摘要:

我们提出了一个物理模型来产生自旋- $s$粒子的多体纠缠态,这些粒子在分布式量子信息处理中有重要的应用。我们的协议是基于一个过程中,移动自旋诱导远程散射中心之间的相互作用。因此,主要优势在于对静止和良好分离的旋转的管理。在可生成的状态中,存在一类$N$ -量子比特单线态,其允许以可扩展和可控的方式进行最佳量子远程克隆。我们还展示了如何准备Aharonov,W和Greenberger-Horne-Zeilinger状态。

英文摘要:

We propose a physical model for generating multipartite entangled states of spin-$s$ particles that have important applications in distributed quantum information processing. Our protocol is based on a process where mobile spins induce the interaction among remote scattering centers. As such, a major advantage lies on the management of stationary and well separated spins. Among the generable states, there is a class of $N$-qubit singlets allowing for optimal quantum telecloning in a scalable and controllable way. We also show how to prepare Aharonov, W and Greenberger-Horne-Zeilinger states.
