Entanglement and correlation of quantum light can enhance LiDAR sensitivity in the presence strong background noise. However, power such sources is fundamentally limited to a stream single photons cannot compete with detection range high-power classical transmitters. To circumvent this, we develop demonstrate quantum-inspired prototype based on coherent measurement time-frequency correlation. This system uses source maintains high noise rejection advantage LiDARs. In particular, show that it...
Non-local effects have the potential to radically move forward quantum enhanced imaging provide an advantage over classical not only in laboratory environments but practical implementation. In this work, we demonstrate a 43dB higher signal-to-noise ratio (SNR) using LiDAR based on time-frequency entanglement compared with phase-insensitive system. Our system can tolerate more than 3 orders of magnitude noise single-photon counting systems before detector saturation dead time 25ns. To achieve...
In this paper, the biometric potential of eye movement and blinking for human recognition task is investigated. These modalities might be useful specific applications like driver authentication law enforcement. For purpose, a database 22 subjects was build where movements blinks were recorded using Gazepoint GP3 while users watching real driving sessions. Eye features extracted from fixations saccades separately. include blink pattern, its speed acceleration patterns, time delineation...
By utilizing quantum temporal correlations in spontaneous parametric down conversion photon pairs, conjunction with non-local dispersion, we can achieve 35 . 94 ± 0 91dB improvement SNR over classical LIDAR.

We demonstrate a quantum-inspired LiDAR based on coherent detection of broadband optical phase correlations. It can effectively reduce in-band noise power by over 100dB while still achieving single photon sensitivity.
