Quasars represent our main lighthouses to explore the high redshift Universe and to investigate the processes of formation of galaxies and their central supermassive black holes. The characterization of the key parameters of quasar hosts as the galaxy mass, size, morphology and their close environments are hindered by the limited resolution and sensitivity of the present instrumentation. We investigate here the expected capabilities of future observations obtained with near-IR Adaptive Optics imaging cameras foreseen for Extremely Large Telescopes. Detailed simulations are presented to evaluate the accuracy of those observations under di erent observing conditions.
