Research Abstract

By constructing a unified theoretical framework, I have generalized the nonequilibrium relations and the second law of thermodynamics for information processing processes including measurement and feedback. Based on it, I have derived the production rates of entropy and information in nonequilibrium steady states of a molecular information machine
