Abstract

The physics of information and computation has been a recognized discipline for several decades. This is not surprising. Information is, after all, encoded in the state of a physical system. Our abilities to compute and process information depend directly on the physics of the system. A computation is something that can be carried out on an actual physically realizable device. Hence the study of information and computation is linked to the study of the underlying physical process. From the perspective of developing state-of-the-art computing technology, study of the principles of physics and material science is essential. From a more abstract and theoretical point of view, there have been noteworthy milestones in our understanding of how physics constrains our ability to use and manipulate information e.g. Landauer's Principle, Reversible Computation, Explanation of Maxwell's Daemon, etc.
