Information Thermodynamics on Causal Networks and Biochemical Information Processing

Abstract

In recent years, the relationship between thermodynamics and information has been intensively studied, leading to an emerging field of “information thermodynamics.” We have derived the second law of information thermodynamics on Bayesian networks, and applied it to biochemical information processing of E. coli chemotaxis. In this article, we review the basic concepts in information thermodynamics and our recent results.
