Quantum Sensing with Correlated Light Sources

Sources of correlated photon pairs have become a valuable resource for imaging, sensing and spectroscopy with recent developments enabled by new advancements in laser technology and nonlinear optics. Photon correlations enable sensing and imaging of fragile samples at very low photon flux. Photon pairs also link diverse spectral ranges, which are limited only by phase matching and the transparency windows of nonlinear materials. At its most powerful, nonlinear interferometry utilizes correlated photon pairs to "sense with essentially undetected photons." This special topic focuses on developments in the field of correlated photon-pair sources and their applications.
