We aim at developing novel imaging instruments that exploit the intrinsic spatio-temporal correlations of astronomical light sources to bring the quantum advantage in space imaging. These novel instruments differ from standard imaging systems in the way images are retrieved. Conventional images are obtained from direct measurement of the intensity of light coming from the object of interest and recorded by a sensor. Here, instead, we first register optical intensities on two disjoint sensors, and then measure correlations between them. After a brief overview on the state of the art of quantum imaging for space objects, we describe the working principle of Correlation Plenoptic Imaging, which enables to perform 3D imaging and refocusing of out-of-focus objects, and a possible application to satellite imaging.

Quantum sensing aims to detect signals with unparalleled sensitivity, potentially surpassing classical limitations. Solid-state spin defects, particularly nitrogen-vacancy centers in diamond, have emerged as promising platforms due to their long coherence time, optical addressability, high field sensitivity, and spatial and spectral resolution, making them ideal for sensing and imaging applications. Their compact size and robust performance under room temperature and ambient conditions further enhance their suitability for real-world applications. We provide an overview of quantum sensing principles and explore efforts to improve sensor functionality, including advanced sensing protocols, spatial imaging techniques, and integration with optical systems to enhance detection efficiency. We also highlight recent progress in the applications of these sensors across various use cases, including biomedical diagnostics, semiconductor device inspection, and industrial and military applications.

We provide an introductory overview of medical and industrial x-ray imaging applications and requirements for readers whose primary background is in quantum imaging. We discuss some opportunities for quantum X-ray imaging and related techniques such as ghost imaging to provide meaningful benefits in imaging and explain some of the key challenges that remain before practical applications can reach end users.
