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 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 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 …

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 …
