What is the best resolution in optical imaging, what is the smallest displacement we can measure, how many bits can read with one focused laser beam? These are all questions that can be discussed with classical optics. However, the quantum nature of light also imposes some new limits. In recent years we have developed many new techniques in quantum optics that allow us to surpass the conventional shot noise limit for intensity and phase measurements. After gaining many new insights into the quantum properties of the detection systems we now have the opportunity address the question of spatial resolution with new tools and possibly even better outcomes.
