Integrated Quantum Photonics Based on Hybrid Superconductor-Semiconductor Nanostructures

量子光子技术将光的量子特性付诸实践。编码在单个光子上的信息不仅提供了增强通信安全性的新机会，而且还提供了执行传感、成像、计算和计量的全新方法。量子光子技术的最好例子是商业上可用的量子密钥分发系统，该系统潜在地增强了点对点光纤通信链路上的信息安全。预计在部署能够产生、检测、传输和处理单光子和纠缠多光子的先进光子设备后，这种系统将扩展到通信网络。

Quantum photonic technology puts the quantum properties of light into practical use. Information encoded on individual photons not only offers new opportunities to enhance the security of communication but also radically new ways to perform sensing, imaging, computation and metrology. The best example of quantum photonic technology is a commercially available quantum key distribution system that potentially enhances the security of information over a point-to-point fiber optic communication link. It is anticipated that such systems will be extended to communication networks upon deployment of advanced photonic devices capable of generation, detection, transmission and processing of single-photons and entangled multi-photons.
