COLLOQUIUM: Optical quantum metrology sensing and imaging (March 2019)

Speaker: Marco Genovese, INRIM Abstract: In the last years the specific properties of quantum states (as entanglement), for long time considered as  peculiarities discussed by the restricted community of physicists interested in the foundations of quantum mechanics, became a fundamental resource for the development of new technologies (as quantum communication, computation and imaging), collectively dubbed “quantum technologies”. In this talk, after a generic introduction, I will introduce in details  the new possibilities in imaging and sensing offered by quantum measurements. In particular I will discuss two fields that we have contributed to explore at INRIM: quantum imaging  (ghost and sub shot noise imaging, quantum illumination) and new paradigms of quantum measurement as  weak and protective  measurements.
