我们提出了一种用于生成自旋粒子多部分纠缠态的物理模型，该模型在分布式量子信息处理中具有重要应用。我们的协议基于移动旋转引起远程散射中心之间交互的过程。因此，一个主要优势在于管理静止且分离良好的旋转。在可生成的状态中，有一类 N 量子位单态，允许以可扩展和可控的方式实现最佳量子远程克隆。我们还展示了如何准备 Aharonov、W 和 Greenberger-Horne-Zeilinger 状态。
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 in 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.
