Applications of squeezed light span quantum technologies, including sensing, communications and computing. Integrated photonics provides scale-up, miniaturisation and increased robustness of optical devices, and various material platforms are being explored for photonic technologies that harness quantum phenomena, including squeezed light. This is due to the phase stability provided for phase sensitive quantum photonic components, such as homodyne detection. However, there is currently no approach to integrate squeezed light generation and quantum light detection into one chip. This project will engineer a scalable and manufacturable integrated photonics platform that generates, manipulates and measures squeezed quantum states of light in one monolithic chip architecture - silicon nitride nano-photonics. This will simplify assembly, miniaturise footprint, and enhance robustness of components for: quantum sensing, quantum communications and continuous variables quantum computing.

压缩光的应用跨越了量子技术，包括传感、通信和计算。集成光子学提供了光学器件的放大、放大和增强的鲁棒性，并且正在探索各种材料平台用于利用量子现象（包括压缩光）的光子技术。这是由于为相位敏感量子光子组件（诸如零差检测）提供的相位稳定性。然而，目前还没有将压缩光产生和量子光检测集成到一个芯片中的方法。该项目将设计一个可扩展和可制造的集成光子学平台，在一个单片芯片架构中生成，操纵和测量光的压缩量子态-氮化硅纳米光子学。这将简化组装，减少占地面积，并增强组件的鲁棒性：量子传感，量子通信和连续变量量子计算。
