Fibre Wavelength Quantum Networks (FQ-Net)

量子通信提供了一种基于基本物理定律的方法来保证跨网络加密数据传输的安全性。与传统密码学不同，量子通信不受未来计算能力和数学进步的影响，这使得量子通信网络成为信息时代保护我们最珍贵和私人数据安全的重要组成部分。该项目旨在解决方案中缺失的一部分，并构建和演示与已建立的点对点链路量子加密系统兼容的低错误量子网络节点。这对于将专用链路的效用扩展到灵活的网络和量子互联网至关重要。我们的方法将基于新兴的半导体电信量子LED技术的发展，该技术与传统的光电子学有着共同的根源。我们的研究计划将开发增强的LED设计，这将彻底改变性能，包括高频操作。最后，我们将开始对我们的系统进行现场测试，在已安装的光纤基础设施上分配量子纠缠LED光。

Quantum communications provides a way to guarantee security of encrypted data transmissions across networks, based on fundamental physical laws. Unlike conventional cryptography, quantum communications are immune to future advances in computing power and mathematics, making quantum communication networks an important part of keeping our most precious and private data safe in the information age. This project aims to address a missing piece of the solution, and build and demonstrate a low error quantum network node compatible with established point-to-point link quantum encryption systems. This is vital to extend the utility of dedicated links to flexible networks, and the quantum internet. Our approach will be based on development of newly emerging semiconductor telecom quantum LED technology, which shares roots with conventional opto-electronics. Our research plan will develop enhanced LED designs that will revolutionise performance, including high frequency operation. Finally, we will begin field testing of our systems, distributing quantum-entangled LED light over installed optical fibre infrastructure.
