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 …

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 …

A Collège de France - CNED coproduction Abstract By associating a method - comparative studies - with a process in progress - the internationalization of law -, this Chair looks to the future, however uncertain that future may be. Admittedly, current …

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 …

The incidence of end-stage renal disease (ESRD) is increasing in the United States (US) population USRDS, and the prevalence of chronic kidney disease also appears to be increasing, in parallel with increased surveillance, routine reporting of estimated …

Abstract This talk summarizes our recent attempts to integrate action and perception within a single optimization framework. We start with a statistical formulation of Helmholtz's ideas about neural energy to furnish a model of perceptual inference and …

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 …

Abstract We present a variational treatment of dynamic models that furnishes the time-dependent conditional densities of a system's states and the time-independent densities of its parameters. These obtain by maximising the variational free energy of the …

Abstract Value-learning and perceptual learning have been an important focus over the past decade, attracting the concerted attention of experimental psychologists, neurobiologists and the machine learning community. Despite some formal connections; e.g. …

The destinies of the Indian and Iranian communities followed distinct readings: for the Parsis, the 19th century was a time of emancipation and wealth. For the Mazdeans of Iran, the 19th century was a time of repression and loss. So the Parsis set about …

Abstract The first lesson presented a general overview of mesoscopic state superpositions in quantum optics. It showed how these superpositions can be generated, either with photons or with atoms. The link with quantum computing was also clarified, by …

There are few texts that, like Quixote , have aroused such an intense and frequent impulse among visual artists towards the desire or necessity of illustration. In the West, perhaps only the Bible and the Divine Comedy could compare with Quixote in the …
