项目摘要

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.
该项目的目标是开发量子力学保持光域到微波域之间的频率转换,用于将量子激光雷达的进展转移到量子雷达。最近,我们小组开发并展示了一种桌面实用的量子增强目标检测,依靠团队的集成量子源和实用的检测系统。这种方法代表了量子照明技术和设备的进一步可能的技术进步,这些技术和设备通过使用集成量子光源而成为可能。随着我们在这一领域的进步,我们设法将量子增强成像的性能提高到比经典成像性能高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两个不同颜色的光子之间转移量子态的能力,这将使我们能够将我们在光域进行的所有记录设置发展转移到微波域。虽然雷达在局部领域(激光雷达)是有吸引力的,并为许多近似值的承诺,固有的限制,如衍射和光场的损失,限制了什么可以实现。
