论文摘要
量子通信技术提供了几种高级策略。但是，它们的实际使用通常尚未得到很好的理解。因此，在这项工作中，我们分析了未来派大型机器人工厂的概念，每个机器人都有与之相关的计算单元。计算单元有助于机器人实时执行的大型计算任务。每个机器人在其计算单元附近随机移动，此外，机器人和单元都可以更改位置。为了最大程度地减少延迟，将连接视为光学无线。由于流动性，假定频段的永久最佳分配可以增加通信延迟，因此被排除在外。在这样的假设下，我们比较了不同类型的此类架构的不同容量缩放，其中一种是利用量子通信技术构建的，另一个是基于常规设计方法的。
Quantum communication technology offers several advanced strategies. However, their practical use is often times not yet well understood. In this work we therefore analyze the concept of a futuristic large-scale robotic factory, where each robot has a computing unit associated to it. The computing unit assists the robot with large computational tasks that have to be performed in real-time. Each robot moves randomly in a vicinity of its computing unit, and in addition both the robot and the unit can change location. To minimize latency, the connection is assumed as optical wireless. Due to the mobility, a permanent optimal assignment of frequency bands is assumed to increase communication latency and is therefore ruled out. Under such assumptions, we compare the different capacity scaling of different types of such architectures, where the one is built utilizing quantum communication techniques, and the other based on conventional design methods.
