Lay summary
Information cannot exist without physical information carriers. For example, when we speak, information is carried by sound waves, when we write, it is represented as ink on a piece of paper, or when we work with a computer, information may take the form of magnetization on the surface of a hard drive. Consequently, the storage and processing of information is ultimately a physical process.That information is always physical has been pointed out by several physicists and information theorists, including for example Rolf Landauer and Richard Feynman. They concluded that the possibilities and limitations of information processing are ultimately determined by the physical laws governing the systems that carry the information. In particular, if the information-carrying systems are quantum-mechanical, a quantum-mechanical treatment of information becomes necessary. This insight eventually led to the development of Quantum Information Theory as a novel research discipline. One of its main aims is to study how the laws of information processing depend on the laws of quantum physics.

The idea underlying this project is, so to speak, to go in the opposite direction, i.e., to study physical systems from an information-theoretic perspective. In particular, we plan to investigate to what extent basic properties of information processing determine the behavior of physical systems. 
This approach is particularly suitable in the context of thermodynamics and statistical mechanics, where the use of information-theoretic notions already has a long tradition, dating back to the work of Maxwell and Szilard. Here, a basic and in general still open question concerns the thermalization of systems, i.e., why and how fast a physical system reaches its thermal equilibrium. This question can, for example, be addressed using techniques that have been developed recently in information theory for the study of randomness. 
There is a variety of areas in physics where information plays a crucial role, ranging from applied problems such as state tomography to foundational questions, e.g., concerning the information-content of physical theories. We expect that, in this project, we can establish information theory as a tool and demonstrate its use to the study of such problems.

Abstract

The main motivation behind this project is to improve our understanding of the inherent connection between physics and information. We intend to establish this connection on a technical level, so that information-theoretic methods can be applied to the study of problems in physics, particularly in the area of thermodynamics and statistical mechanics. For this, we will use novel information-theoretic approaches, such as the smooth entropy calculus as well as the decoupling technique.
