The physics of information: from Maxwell's demon to Landauer
Prof. Dr. Eric Lutz (Department für Physik, Friedrich-Alexander-Universität, Erlangen-Nürnberg)
We will discuss the intimate connection existing between information theory and thermodynamics following its historical development. We will focus on two complementary aspects: 1) the gain of information which we will illustrate with Maxwell's famous demon and 2) the erasure of information summarized by Landauer's principle. We will further present a number of recent single-particle experiments that have for the first time realized the above gedanken experiments in the lab.
