Quantum imaging by synthesis of multimode quantum light

An optical image can contain a wealth of information frequently amounting to the equivalence of millions of pixels. From a quantum-mechanical point of view, such images can be described by a quantum state that spans as many transverse modes as pixels [1]. Quantum imaging is therefore the archetype of highly multimode quantum optics. To date, most of the quantum imaging ideas and experiments aim to produce light that is at the same time nonclassical and highly multimode [2, 3]. These fascinating multimode features can be a source of theoretical complications and experimental difficulties.
