摘要:

我们提出了一个纠缠态量子密码系统,第一次在现实世界中的应用场景。完整的密钥生成协议在两个分布式嵌入式硬件设备之间实时执行,这两个设备通过1.45公里的光纤连接,安装在维也纳污水系统中进行本实验。生成的量子密钥立即被移交并由安全通信应用程序使用。

英文摘要:

We present an entangled-state quantum cryptography system that operated for the first time in a real world application scenario. The full key generation protocol was performed in real time between two distributed embedded hardware devices, which were connected by 1.45 km of optical fiber, installed for this experiment in the Vienna sewage system. The generated quantum key was immediately handed over and used by a secure communication application.
