Merging-Based Quantum Repeater

Maria Flors Mor-Ruiz, Jorge Miguel-Ramiro, Julius Wallnöfer, Tim Coopmans, Wolfgang Dür

AI总结:

本文提出一种基于量子合并操作和纠缠重用的量子中继器方案,在操作失败后仍保留纠缠,从而降低等待时间、提高通信速率,并通过原理验证展示其优于传统交换式中继协议的实际应用潜力。

摘要:

我们引入一种基于生成规模不断增长的纠缠态的量子中继器替代设计方案。该方案利用量子合并操作(也称为 I 型融合操作),允许纠缠的重新整合与再利用。与传统的基于交换的协议不同,我们的方法在操作失败后仍保留纠缠,从而减少等待时间、实现更高的速率,并在通信请求中引入更强的灵活性。通过原理验证分析,我们证明了该方法相对于标准中继器协议的优势,突显了其在实际量子通信场景中的潜力。

英文摘要:

We introduce an alternative approach for the design of quantum repeaters based on generating entangled states of growing size. The scheme utilizes quantum merging operations, also known as fusion type-I operations, that allow the reintegration and reuse of entanglement. Unlike conventional swapping-based protocols, our method preserves entanglement after failed operations, thereby reducing waiting times, enabling higher rates, and introducing enhanced flexibility in the communication requests. Through proof-of-principle analysis, we demonstrate the advantages of this approach over standard repeater protocols, highlighting its potential for practical quantum communication scenarios.
