Paper Abstract

We experimentally demonstrate quantum imaging where the images are stored in both space and time. Quantum images of remote objects are produced with either one or two beams of chaotic laser light and two sensors measuring the reference field and bucket field at different space-time points. Chaotic laser light is produced by laser light passing through rotating ground glass. Experiments were performed in both turbulent and nonturbulent conditions. Interestingly, quantum images are produced using the two sensors of quantum imaging when both single and double beams are implemented in the experimental setup. Also, we observed that the quantum images move depending on the time delay between the sensor measurements. The experiments provide a new testbed for exploring the time and space scale fundamental physics of quantum imaging and suggest new pathways for quantum information storage and processing. The research is applicable to making ghost imaging movies of moving objects and implementation of space-time imaging for enhanced imaging.
