The difference in level between the instrumental score and the score of electro-acoustic transformations is due to the fact that an instrument/an ensemble of instruments directly produces a sound object determined by the writing (first-degree activity, …

Abstract The ninth and tenth lessons tackled the experimental aspect of this field of research by briefly describing a set of experiments recently carried out at ENS, in which qubits are carried by Rydberg atoms passing one by one through a …

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 seventh and eighth lessons provided an introduction to quantum computation. Elementary logic gates were described, and it was shown that two-qubit gates are universal, in the sense that all unitary operations on a qubit system can be …

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 …
