量子通信：构建无法破解的未来网络
英文原文
Quantum communication leverages the laws of quantum mechanics to create unbreakable encryption, where any eavesdropping attempt instantly alters transmitted data. Quantum Key Distribution (QKD) networks now span thousands of kilometers, with China’s Micius satellite enabling intercontinental secure communication. Breakthroughs like quantum repeaters and memory relays are overcoming distance limits, while quantum internet prototypes achieve 90% entanglement fidelity across cities.
Critical applications include:
- Nuclear command systems immune to cyber warfare
- Banking transaction tunnels with zero interception risk
- Health data highways protecting genetic privacy
Yet quantum hacking exploits hardware flaws, and quantum supremacy threatens current encryption. The US-China tech cold war intensifies as NATO deploys QKD submarines, while China’s ”Great Wall” quantum backbone aims to cover 20,000km by 2025.

量子通信运用量子力学定律打造无法破解的加密系统，任何窃听行为都会瞬间改变传输数据。量子密钥分发（QKD） 网络已延伸数千公里，中国墨子号卫星实现洲际安全通信。量子中继器与量子存储器突破距离限制，量子互联网原型在城市间实现90%量子纠缠保真度。
核心应用场景：
- 核指挥系统免疫网络战攻击
- 银行交易通道零截获风险
- 医疗数据专线保护基因隐私
但量子黑客利用硬件漏洞攻击，量子霸权威胁现行加密体系。中美科技冷战升级：北约部署QKD潜艇，中国”量子长城”骨干网2025年将覆盖2万公里。
