Quantum limits in image processing
Vincent Delaubert, Nicolas Treps, Claude Fabre +2
We determine the bound to the maximum achievable sensitivity in the estimation of a scalar parameter from the information contained in an optical image in the presence of quantum n…
TEM10 homodyne detection as an optimal small displacement and tilt measurements scheme
Vincent Delaubert, Nicolas Treps, Mikael Lassen +4
We report an experimental demonstration of optimal measurements of small displacement and tilt of a Gaussian beam - two conjugate variables - involving a homodyne detection with a…
Generation of Squeezing in Higher Order Hermite-Gaussian Modes with an Optical Parametric Amplifier
Mikael Lassen, Vincent Delaubert, Charles C. Harb +3
We demonstrate quantum correlations in the transverse plane of continuous wave light beams by producing -4.0 dB, -2.6 dB and -1.5 dB of squeezing in the TEM00, TEM10 and TEM20 Herm…
A quantum study of multi-bit phase coding for optical storage
Magnus T. L. Hsu, Vincent Delaubert, Warwick P. Bowen +3
We propose a scheme which encodes information in both the longitudinal and spatial transverse phases of a continuous-wave optical beam. A split detector-based interferometric schem…
Optical storage of high density information beyond the diffraction limit : a quantum study
Vincent Delaubert, Nicolas Treps, Gao Bo +1
We propose an optical read-out scheme allowing a demonstration of principle of information extraction below the diffraction limit. This technique, which could lead to improvement i…
Quantum measurements of spatial conjugate variables: Displacement and tilt of a Gaussian beam
Vincent Delaubert, Nicolas Treps, Charles C. Harb +2
We consider the problem of measurement of optical transverse profile parameters and their conjugate variable. Using multi-mode analysis, we introduce the concept of detection noise…
