Coincidence Counting of Quantum Gabor Holography

ABSTRACT Quantum imaging leverages the intrinsic sharpness of quantum correlations between entangled photon pairs, offering the potential for high spatial resolution and enhanced signal‐to‐noise performance. However, practical quantum imaging systems often suffer from complex optical architectures and long acquisition times, limiting their applicability in dynamic scenarios. In this work, we propose quantum Gabor holography (QGH) and introduce array‐based coincidence counting with joint probability analysis to directly extract the spatial correlations of entangled photon pairs. The system selectively identifies true photon‐pair events while effectively suppressing uncorrelated background photons and detector noise. Experiments confirm that correlation‐based QGH preserves intrinsic quantum spatial information, improves noise robustness, and enables reliable amplitude and phase reconstruction even under ultra‐weak photon flux. The proposed method provides an efficient and physically grounded pathway toward lensless, low‐light, and high‐resolution quantum imaging.
