    "abstract": "We investigate analytically and numerically the role of quantum fluctuations\nin reconstruction of optical objects from diffraction-limited images. Taking as\nexample of an input object two closely spaced Gaussian peaks we demonstrate\nthat one can improve the resolution in the reconstructed object over the\nclassical Rayleigh limit. We show that the ultimate quantum limit of resolution\nin such reconstruction procedure is determined not by diffraction but by the\nsignal-to-noise ratio in the input object. We formulate a quantitative measure\nof super-resolution in terms of the optical point-spread function of the\nsystem.",
