    "abstract": "We address several estimation problems in quantum optics by means of the\nmaximum-likelihood principle. We consider Gaussian state estimation and the\ndetermination of the coupling parameters of quadratic Hamiltonians. Moreover,\nwe analyze different schemes of phase-shift estimation. Finally, the absolute\nestimation of the quantum efficiency of both linear and avalanche\nphotodetectors is studied. In all the considered applications, the Gaussian\nbound on statistical errors is attained with a few thousand data.",
