  Single-photon-avalanche diode (SPAD) arrays are essential tools in
biophotonics, optical ranging and sensing and quantum optics. However, their
small number of pixels, low quantum efficiency and small fill factor have so
far hindered their use for practical imaging applications. Here, we demonstrate
full-field entangled photon pair correlation imaging using a 100-kpixels SPAD
camera. By measuring photon coincidences between more than 500 million pairs of
positions, we retrieve the full point spread function of the imaging system and
subsequently high-resolution images of target objects illuminated by spatially
entangled photon pairs. We show that our imaging approach is robust against
stray light, enabling quantum imaging technologies to move beyond laboratory
experiments towards real-world applications such as quantum LiDAR.
