La dynamique de Zénon quantique permet de confiner l'évolution d'un système à un sous-espace choisi de son espace de Hilbert par la mesure répétitive d'une observable convenable. Cette dynamique restreinte peut être très contre-intuitive et conduire à la préparation d'états non classiques. Nous décrivons une expérience réalisant cette dynamique dans une multiplicité de Rydberg et proposons une méthode pour l'observer dans le contexte de l'électrodynamique quantique en cavité. Dans les deux cas, la dynamique de Zénon ouvre des perspectives intéressantes pour la métrologie quantique et l'étude de la décohérence.

Quantum Zeno Dynamics restricts the evolution of a system in a tailorable subspace of the Hilbert space by repeated measurements of a proper observable. This restricted dynamics can be counterintuitive and lead to the generation of interesting nonclassical states. We describe an experiment implementing the Zeno dynamics in an atomic Rydberg level manifold, and we propose an implementation in the cavity quantum electrodynamics context. Both systems open promising perspectives for quantum-enabled metrology and decoherence studies.
