摘要

在未来量子互联网的节点之间产生预示纠缠是释放量子通信潜力的基本操作。在本文中,我们提出了一种在链路层经典控制面上运行的去中心化同步协议(decentralized synchronizationprotocol),以应对在少量子比特量子网络节点间产生预示纠缠的协调挑战。此外,通过使用 NetSquid 进行量子网络仿真,我们发现与天真的分布式队列方法相比,我们的协议实现了更低的纠缠请求延迟。我们观察到,随着量子网络链接数量的增加,平均请求延迟增长降低了六倍。最终同步协议(ESP)允许节点在多对等量子网络中以可扩展的方式协调预示纠缠的产生。据我们所知,这是第一个用于管理预示纠缠请求的去中心化同步协议。

Synchronization Control-Plane Protocol for Quantum Link Layer
Heralded entanglement generation between nodes of a future quantum internet is a fundamental operation that unlocks the potential for quantum communication. In this paper, we propose a decentralized synchronization protocol that operates at the classical control-plane of the link layer, to navigate the coordination challenges of generating heralded entanglement across few-qubit quantum network nodes. Additionally, with quantum network simulations using NetSquid, we show that our protocol achieves lower entanglement request latencies than a naive distributed queue approach. We observe a sixfold reduction in average request latency growth as the number of quantum network links increases. The Eventual Synchronization Protocol (ESP) allows nodes to coordinate on heralded entanglement generation in a scalable manner within multi-peer quantum networks. To the best of our knowledge, this is the first decentralized synchronization protocol for managing heralded entanglement requests.
