A practical, high-brightness quantum illumination for unspoofable LIDAR


Project Description

Radar has provided an essential underpinning technology to enable rapid determination of an objects position, angle and velocity at long range using microwaves. Using lasers these techniques have been extended to perform LIDAR at optical wavelengths, offering 3D mapping and improved spatial resolution. However, in applications where there is a requirement to operate undetected to identify targets engineered for low reflectivity, the resulting return signal is very weak and can be easily lost within a noisy background environment or even suppressed using active jamming from the target. In this regime of low signal level and strong background, quantum illumination (QI) using correlated light offers an enhanced signal-to-noise compared to classical sources, and is robust against jamming.

In this project we will develop a novel compact and high brightness source of correlated single photons for studies of QI using a source with high (GHz) repetition rate and dynamically adjustable frequency and temporal properties to enable proof-of-principle demonstration and quantification of the superiority of QI against classical illumination. We will then develop and test new protocols to engineer a system robust against jamming from external sources. In addition to advancing the field of quantum radar, the compact photon source can be exploited for applications in free-space quantum communication.

The PhD will be carried out in the Experimental Quantum Optics and Photonics Group in the Physics Department at the University of Strathclyde, working alongside members of the Computational and Non-linear Quantum Optics group to provide theoretical support.
