Final Report Summary - GEQIT (Generalized (quantum) information theory)
This goal has now been achieved. The core technical ingredient for this is a novel notion of entropy, which generalises both information-theoretic and thermodynamic entropy. To demonstrate its use, we have shown, for instance, that it correctly quantifies the amount of heat that is generated in logically irreversible processes, or that it characterises the information-theoretic conditions under which thermodynamic systems thermalise. This establishes a quantitative link between quantities defined in information theory and quantities relevant to thermodynamics.
