论文摘要
近年来，量子通信研究已转变为包括多目标网络，量子网络路由自然出现的问题。为了了解多目标路由的潜力，我们专注于未来量子网络的最有前途的架构 - 那些连接节点的结构相互接近。在不同的通信方案下，已经研究了诸如环，线条和网格之类的最近的网络，以促进量子资源的共享，尤其是在瓶颈存在下。在这里，我们通过证明环和线无法克服常见的瓶颈交流问题来分析最近邻近量子网络的潜力并确定一些严重的限制。
Quantum communication research has in recent years shifted to include multi-partite networks for which questions of quantum network routing naturally emerge. To understand the potential for multi-partite routing, we focus on the most promising architectures for future quantum networks - those connecting nodes close to each other. Nearest-neighbour networks such as rings, lines, and grids, have been studied under different communication scenarios to facilitate the sharing of quantum resources, especially in the presence of bottlenecks. We here analyze the potential of nearest-neighbour quantum networks and identify some serious limitations, by demonstrating that rings and lines cannot overcome common bottleneck communication problems.
