Compressive Object Tracking using Entangled Photons

TL;DR

This paper introduces a quantum imaging method using compressive sensing and ghost imaging to track moving objects at low light levels, significantly reducing measurement requirements compared to traditional raster scans.

Contribution

It presents a novel compressive sensing protocol integrated with ghost imaging for efficient, low-light object tracking with fewer measurements and photons.

Findings

Tracks moving objects with less than 3% measurements of raster scan

Operates effectively at low photon levels

Reduces measurement and photon count significantly

Abstract

We present a compressive sensing protocol that tracks a moving object by removing static components from a scene. The implementation is carried out on a ghost imaging scheme to minimize both the number of photons and the number of measurements required to form a quantum image of the tracked object. This procedure tracks an object at low light levels with fewer than 3% of the measurements required for a raster scan, permitting us to more effectively use the information content in each photon.
