Information quantique

Recent years have seen enormous experimental progress in preparing, controlling and probing quantum systems in various regimes far from thermal equilibrium. Examples include systems as ultra-cold atomic quantum gases under time-dependent perturbations, driven non-linear cavity QED systems or strongly correlated electrons in solid-state materials under ultra-fast optical excitations.

The goal of this course is to introduce the main concepts and challenges of quantum computing, a new set of technologies and techniques that promise to solve hard computational problems.

Quantum information combines quantum physics and information theory, leading to a conceptual shift in both disciplines. By implementing quantum protocols in physical systems and reformulating quantum physics in terms of information and logical operations, we gain powerful tools to investigate the distinctive features of quantum mechanics - such as its divergence from classical physics and the nature of the quantum-to-classical transition.
