Abstract:
Starting from the birth of statistical mechanics, the linkage between thermodynamics and information is a field alive with many discussions and a large variety of (discording) interpretations. The most accepted framework is the one formulated by Bennett which states a one-to-one relationship between thermodynamic and logic reversibility. In this talk, critical failures of this relationship are analyzed by using arguments taken from recent papers by Sagawa. In particular it will be proven that thermodynamic entropy and information are not interchangeable. Some other critical points of Bennett claims will also be presented as the basic ideas behind an experiment now performed in Perugia.
