Efficiently converting between optical and microwave photons using nano-photonics

该项目的目标是开发光域到微波域之间的量子力学保持频率转换，用于将量子激光雷达的进步转移到量子雷达。最近，我们的团队开发并展示了一个桌面实用的量子增强目标探测，依赖于团队的集成量子源和实用的探测系统。这种方法代表了通过使用集成量子光源而可能实现的量子照明技术和设备的进一步可能的技术进步。随着我们在这一领域的进步，保持世界纪录，我们设法将量子增强成像的性能提高到比经典成像的性能高45 dB。这是通过使用新型的非局域色散以及集成源来实现的。如果我们能够获得在不同颜色的两个光子之间转移量子态的能力，这将使我们能够将我们在光学领域进行的所有记录设置开发转移到微波领域。虽然局部领域的雷达（LiDAR）很有吸引力，并有望实现许多近似，但固有的局限性，如衍射和光场损失，限制了可以实现的目标。

The objective of this project is to develop quantum mechanically preserving frequency conversion between the optical domain to the microwave domain to use in transferring quantum LiDAR advances to quantum radar.Recently our group developed and demonstrated a tabletop practical Quantum enhanced target detection relying on the team's integrated quantum source and a practical detection system. This approach is representative of further possible technological advances in quantum illumination techniques and devices made possible by the use of integrated quantum light sources. As we progress in this field to hold world records, we managed to increase the performance of quantum enhanced imaging up to 45dB better than the performance of classical imaging. This was carried out by using novel non-local dispersion as well as integrated sources.If we are able to obtain the ability to transfer of quantum states between two photons at different colors, this would allow us to transfer all the record setting developments we carried out in the optical domain to the microwave domain. While radar in the topical domain (LiDAR) is attractive and holds promise for many approximations, the inherent limitations such as diffraction and losses of optical fields pose limits on what can be achieved.
