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传输到量子雷达。最近，我们团队依靠团队集成的量子源和实用的探测系统，开发并演示了一种桌面实用的量子增强目标探测。这种方法代表了通过使用集成量子光源使量子照明技术和设备成为可能的进一步技术进步。随着我们在这一领域保持世界纪录的进步，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出45dB。这是通过使用新的非局部色散和集成源来实现的。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创造发展转移到微波领域。虽然局部域雷达(LiDAR)很有吸引力，并有望实现许多近似，但固有的局限性，如光场的绕射和损失，对其实现构成了限制。

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.
