Silicon Photonic Platform for Quantum Encryption and Communications

在国防环境中，安全通信链路的完整性可能意味着生死之别。在民用领域，电子金融交易的安全也是防范“网络”盗窃的关键。使用独特的量子“噪声”作为密钥对数据进行加密已被认为是一种非常强大的方法。可以容易地检测到在传输期间截取密钥的尝试。 量子密钥传输已经得到了演示，但需要昂贵、笨重和奇异的设备。该项目将探索低成本、基于硅芯片的量子密钥传输模块。我们的目标是让量子加密变得简单，就像在标准计算机或便携式设备上添加扩展卡一样简单。

The integrity of a secure communications link can mean the difference between life and death in a defence environment. In the civilian arena, the security of electronic financial transactions is also critical to guard against 'cyber' theft. Encryption of data using unique quantum 'noise' as a key has been proposed as an exceptionally strong approach. Attempts to intercept the key during transmission can easily be detected. Quantum key transmission has been demonstrated but requires impractically expensive, bulky and exotic equipment. This project will explore low-cost, silicon chip based quantum key transfer modules. Our aim is to render quantum encryption as simple as adding an expansion card to a standard computer or portable device.
