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与死的区别。 在民用竞技场，电子金融交易的安全性对于防范“网络”盗窃也至关重要。 使用独特的量子“噪声”作为密钥的数据加密已经被提出作为一种非常强大的方法。在传输过程中拦截密钥的尝试很容易被检测到。 量子密钥传输已经被证明，但需要不切实际的昂贵，笨重和异国情调的设备。该项目将探索基于低成本硅芯片的量子密钥传输模块。我们的目标是使量子加密变得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.
