摘要
資訊 processing typically occurs via the composition of modular units, such as the universal logic gates found in discrete computation circuits. The benefit of modular 資訊 processing, in contrast to globally integrated 資訊 processing, is that complex computations are more easily and flexibly implemented via a series of simpler, localized 資訊 processing operations that only control and change local degrees of freedom. We show that, despite these benefits, there are unavoidable 熱力學 costs to modularity-costs that arise directly from the operation of localized processing and that go beyond Landauer's bound on the work required to erase 資訊. Localized operations are unable to leverage global correlations, which are a 熱力學 fuel. We quantify the minimum irretrievable dissipation of modular computations
