摘要
We consider the additional 熵 production (EP) incurred by a fixed 量子 or classical process on some initial state ρ, above the minimum EP incurred by the same process on any initial state. We show that this additional EP, which we term the “mismatch cost of ρ,” has a universal 資訊-theoretic form: it is given by the contraction of the relative 熵 between ρ and the least-dissipative initial state φ over time. We derive versions of this result for integrated EP incurred over the course of a process, for trajectory-level fluctuating EP, and for instantaneous EP rate. We also show that mismatch cost for fluctuating EP obeys an integral fluctuation theorem. Our results demonstrate a fundamental relationship between 熱力學 irreversibility (generation of EP) and logical irreversibility (inability to know
