Implementation of single-photon imaging using entanglement source

Abstract

Light detection has become popular since electronic circuits have become more accurate. Long-range active imaging has been converted in a difficult challenge because the signal degrades significantly while the distance increase. The use of lasers as a signal generator for the detection of objects, as well as algorithms for image reconstruction, provides a new form of capturing an image. In this work, we propose and demonstrate a new schematic system using a low power laser. It can reduce the number of equipment using a single pathway to send and receive the signal. The system was verified by experiments at different distances and also two other type of laser source. Not only doing single photon imaging experiment but also we propose a new quantum ghost imaging system using entangled source. To show how much the quality of the picture can be increase, we implement a simulation to compare Classical Ghost Imaging and Quantum Ghost Imaging. After all the results, we suggest the type of source that can be used to improve our system.
