The purpose of this thesis is to develop tools of noncommutative harmonic analysis. More precisely, it deals with noncommutative Khintchine inequalities and operator-valued singular integrals. The first part is dedicated to questions of interpolation between classical Lp-spaces. We generalize and state new characterisations of interpolation spaces between Lp-spaces. In a second part, we introduce a form of the noncommutative Khintchine inequalities which holds in every interpolation space between two Lp-spaces. It enables us to unify the cases p 2 and to deal with weak Lp-spaces even when p = 1 or 2. By relying on the first part, we characterize spaces in which the usual formulas for Khintchine inequalities hold. In a last part, we give a ...
