Abstract
We study the topic of non-linear light-matter interaction for the generation of multi-photon entangled states. In particular, we want the quantum correlations to be inherent in the Orbital Angular Momentum (OAM) degree of freedom. Our first proposal is to generate four photons, multidimensional, spatially-entangled states, while the final goal is to make them interact with nanostructures for quantum metrology applications.
