This study falls within the field of quantum imaging. Photon-pair correlations in spontaneous parametric down conversion processes are ubiquitous in quantum photonics and its applications. In this work, researchers structure these correlations in the form of images of arbitrarily chosen objects. They show that their approach works with both amplitude and phase objects, even when the beam intensity is also spatially shaped. Furthermore, they demonstrate that - in certain cases - the transmission of quantum correlations-encoded images through scattering media is more efficient than using classical light. Their approach enables the transmission of complex, high-dimensional information using in quantum correlations of photons, which can be useful for developing quantum communication and imaging protocols.
