TL;DR
This paper develops a comprehensive theory of signal-to-noise ratio in bipartite ghost imaging using classical and quantum light, validated by experimental comparisons for thermal and twin beam sources.
Contribution
It provides the first complete theoretical framework for SNR in bipartite ghost imaging with both classical and quantum light sources.
Findings
The theory matches experimental results for twin beams and thermal light.
Quantum twin beams show improved SNR over classical thermal light.
The analysis identifies key factors influencing SNR in ghost imaging.
Abstract
We present a complete and exhaustive theory of signal-to-noise-ratio in bipartite ghost imaging with classical (thermal) and quantum (twin beams) light. The theory is compared with experiment for both twin beams and thermal light in a certain regime of interest.
