However, for a wide class of non-interferometric phase imaging/retrieval methods vastly used in the classical domain e.g., ptychography and diffractive imaging, a demonstration of quantum advantage is still missing. Here, we fill this gap by exploiting entanglement to enhance imaging of a pure phase object in a non-interferometric setting, only measuring the phase effect on the free-propagating field. This method, based on the so-called \"transport","authors_text":"Alberto Paniate, Carmine Napoli, Giuseppe Ortolano, Ivano Ruo Berchera, Marco Genovese, Pauline Boucher, Sarika Soman, Silvania F.
