Given tremendous progress in controlling individual photons and other excitations such as spin, excitonic, phononic in solid-state systems, it is intriguing to explore whether these quantum optical control techniques could pave a radically new way to prepare, detect and manipulate non-local and correlated electronic states. As the first example, I discuss recent observations of various charge and spin order correlations in optical and electrical tunable Bose-Fermi mixtures in hetero-bilayer systems. Secondly, I report on the optical manipulation of quantum Hall states in graphene using twisted light. Specifically, we show that, by going beyond the dipole- approximation in light-matter interaction, one can optically manipulate the electronic wave function.
