量子网络路由协议的建模与设计

Modeling and Designing Routing Protocols in Quantum Networks

Shouqian Shi, Chen Qian

摘要:

量子网络实现了许多重要的应用,例如量子密钥分发。量子网络的基本功能是实现两个远程通信方之间的长距离量子纠缠。本文研究了纠缠路由问题,其目标是通过多跳为并发的源-目的对建立长距离的纠缠。与现有的基于特殊网络拓扑结构的传统纠缠路由算法不同,本文提出了一个综合反映量子网络与经典网络差异的纠缠路由模型,并利用量子网络的独特性质提出了新的纠缠路由算法。评估结果表明,所提出的算法Q-CAST增加了成功的长距离纠缠的数量相比,其他方法有很大的利润。本文所建立的模型和仿真器可以鼓励更多的网络研究人员研究纠缠路由问题。

英文摘要:

Quantum networks enable a number of important applications such as quantum key distribution. The basic function of a quantum network is to enable long-distance quantum entanglement between two remote communication parties. This work focuses on the entanglement routing problem, whose objective is to build long-distance entanglements for the concurrent source-destination pairs through multiple hops. Different from existing works that analyzes the traditional routing techniques on special network topologies, we present a comprehensive entanglement routing model that reflects the differences between quantum networks and classical networks and new entanglement routing algorithms that utilize the unique properties of quantum networks. Evaluation results show that the proposed algorithm Q-CAST increases the number of successful long-distance entanglements by a big margin compared to other methods. The model and simulator developed by this work may encourage more network researchers to study the entanglement routing problem.
