Abstract In the fourth lecture , we established the expression of field operators in frequency space, based on the decomposition of the signal into waves of well-defined wave vectors. The commutator of these field operators is singular : it is given by a …

Abstract The sixth lesson showed in a general way how the sharing of pairs of entangled particles between two parties ("Alice and Bob") makes it possible to perform operations impossible in classical information (secure cryptographic key sharing, quantum …

Abstract The fifth lesson addressed the question of how to measure entanglement by introducing the concepts of Shannon and von Neumann entropy. In a two-part system, the entropy associated with each part (calculated from their reduced density matrix) is a …

Abstract The third lesson was devoted to the decomposition of a signal propagating along a transmission line into orthogonal discrete modes. We introduced the basic concepts of wavelet theory. It is remarkable that a signal of finite energy can be …

Abstract The third and fourth lessons discussed the link between entanglement, decoherence and complementarity by describing and analyzing simple quantum interference and measurement situations. The concept of complementarity expresses the fact that the …

A Collège de France - CNED coproduction Abstract The physiology of the auditory system, and in particular that of the first relays in sound signal processing, is fairly well understood. In the early 1990s, however, the cellular and molecular mechanisms …
