Apparaît dans la collection : Séminaire Poincaré XXIII - L'information

We summarize recent experimental and theoretical progress achieved in the physics of information. We highlight the intimate connection existing between information and energy from Maxwell’s demon and Szilard’s engine to Landauer’s erasure principle. We will focus mainly on experiments on classical systems and we will shortly discuss a few aspects of quantum systems. We conclude by discussing applications in engineering and biology.
