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…
Squeezing frequency combs
German J. De Valcarcel, Giuseppe Patera, Nicolas Treps +1
We have developed the full theory of a synchronously pumped type I optical parametric oscillator (SPOPO). We derive expressions for the oscillation threshold and the characteristic…
