Full textIn the setting of quantum optics, the reconstruction of the quantum state (Wigner function or infinite-dimensional density matrix) of a light beam can be seen as a statistical severely ill-posed inverse problem. First, we propose estimators of the density matrix and the Wigner function respectively, using pattern functions in the first case and kernel functions in the second. We assume that the unknown density matrix belongs to a nonparametric class which corresponds to typical states prepared in the laboratory. We translate these classes in terms of properties of the associated Wigner function. In an other part, we estimate the integrated squared Wigner function by a kernel-based second order U-statistic on a larger regularity class. This quadratic functional is a physical measure of the purity of the state. We deduce an adaptive estimator for the Wigner function that does not depend on the smoothness parameters. In the last part of the thesis, we are interested in the problem of goodness-of-fit testing. We give a testing procedure derived from a projection-type estimator on \textit{pattern} functions. We study the upper bounds of the minimax risk for all our procedures. The density matrix estimation and the testing procedure are implemented and their numerical performances are studied

Full textThis dissertation deals with Bayesian nonparametric statistics, in particular nonparametric mixture models. The manuscript is divided into a general introduction and three parts on rather different aspects of mixtures approaches (sampling, asymptotic, inverse problem). In mixture models, the parameter to infer from the data is a function. We set a prior distribution on an abstract space of functions through a stochastic integral of a kernel with respect to a random measure. Usually, mixture models were used primilary in probability density function estimation problems. One of the contributions of the present manuscript is to use them in regression problems.In this context, we are essentially concerned with the following problems :- Sampling of the posterior distribution- Asymptotic properties of the posterior distribution- Inverse problems, in particular the estimation of the Wigner distribution from Quantum Homodyne Tomography measurements

Full textControllably producing optical photons and making them interact are two key requirements for the development of long-distance quantum communications, and more generally for photonic quantum information processing. This thesis presents experimental studies on possible solutions to these two problems, using the conversion of the photons into collective excitations (polaritons) in a cold atomic cloud, inside the mode of a low-finesse optical cavity (~100). Firstly, ground-state polaritons are used to store a single excitation in the cloud memory. This polariton is then efficiently converted into a single photon, whose field is characterized via homodyne tomography. The single photon state’s Wigner function is reconstructed from the experimental data and exhibits negative values, demonstrating that the photon’s degrees of freedom (spatio-temporal mode and quantum state) are well controlled. Secondly, photons can be coupled to polaritons involving Rydberg states. The strong dipolar interactions between these give rise to very strong optical dispersive nonlinearities, that are characterized in a classical excitation regime. These nonlinearities can be amplified until a single photon is enough to modify the entire system’s response, allowing in principle for the generation of effective photon-photon interactions
