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.
