The eighth and ninth lessons were devoted to Schrödinger cats produced in cavity quantum electrodynamics experiments. An atom interacts with the field stored in a high-surge cavity, and its strongly non-linear coupling with the field produces photonic …

The seventh lesson was devoted to the study of nonlinearities in Bose Einstein condensates, due to interactions between atoms. These interactions, linked to elastic collisions in the sample, have the effect of introducing a non-linear term into the …

The sixth lesson dealt with the study of matter waves (atomic optics). For some years now, we've been able to produce ultra-cold samples of atoms forming Bose Einstein condensates, in which a large number of atoms are all in the same wave function, with …

Effective blood pressure control, especially of the systolic component, is of primary importance in both primary and secondary prevention of Cardiovascular and Cerebrovascular Events. Similarly, systolic blood pressure control is important in the primary …

The fifth lesson described field states in phase space, introducing two important functions defined in this space, Wigner's Q-function and W-function. These functions provide a pictorial and intuitive description of Fock states, coherent states and their …

The fourth lesson addressed the problem of non-linear splitters in quantum optics. After noting that the photon distribution achieved in the final channels of a linear splitter did not in any case allow the realization of a mesoscopic superposition of the …

The third lesson dealt with the analysis of interference experiments in quantum optics. It began with a description of the linear splitter blades that are essential ingredients in these experiments. It is these blades that separate and recombine the …

Detection methods active detector: reacts by making decisions according to a deterministic or indeterministic method (there are a multitude of paths to positive detection); passive detector: reacts blindly (there is only one path to positive detection). …

What we commonly understand today by the notion of theme comes to us essentially from the 20th century, in the sense that themes are not only at the origin of musical discourse and its development, but are also bearers of meaning: symbolic, anecdotal, …

The second lesson recalled the principles of quantum optics. It is indeed in this field that coherent mesoscopic superpositions have been most convincingly studied and prepared, and it is therefore very useful to understand the general concepts of quantum …
