Etude de tests du caractère quantique de systèmes de dimension supérieur à deux dans des conditions réalistes

Abstract : The subject of this thesis is a study of tests of the quantum features of systems of dimension greater than two under realistic conditions. Non-locality is one of the quantum properties used in protocols in the field of quantum communications. The study on the effects of the decoherence (models ofrealistic conditions) address the issue of the conservation of non-locality in practice. Contextuality is another fundamental quantum property with a potential power in quantum information processing. A contextuality test has been developed for all dimensions of quantum systems greater than two. An experiment that considers the experimental issues of contextuality tests is also proposed.
