摘要

量子纠缠是量子网络中量子通信和分布式信息处理的重要资源。然而，网络上的远程发电存在不可避免的传输损耗和其他技术难题。本文介绍了纠缠缓冲的概念，作为准备长距离纠缠的潜在原语。我们研究了通过SWAP相互作用填充一个贝尔态或一个贝尔态流的纠缠缓冲。我们说明了它们对不完美相互作用、噪声和损失的弹性，使缓冲适合于现实的量子网络场景。此外，更大的缠结缓冲总是可以增强这些好处。

Robust entanglement buffers based on SWAP interactions

Quantum entanglement is the essential resource for quantum communication and distributed information processing in a quantum network. However, the remote generation over a network suffers from inevitable transmission loss and other technical difficulties. This paper introduces the concept of entanglement buffers as a potential primitive for preparing long-distance entanglement. We investigate the filling of entanglement buffers with either one Bell state or a stream of Bell states via SWAP interactions. We illustrate their resilience to imperfect interactions, noise, and losses, making the buffers suitable for a realistic quantum network scenario. Additionally, larger entanglement buffers can always enhance these benefits.

期刊介绍： Driven by advances in technology and experimental capability, the last decade has seen the emergence of quantum technology: a new praxis for controlling the quantum world. It is now possible to engineer complex, multi-component systems that merge the once distinct fields of quantum optics and condensed matter physics. Quantum Science and Technology is a new multidisciplinary, electronic-only journal, devoted to publishing research of the highest quality and impact covering theoretical and experimental advances in the fundamental science and application of all quantum-enabled technologies.
