有限模型的基本热力学边界

The fundamental thermodynamic bounds on finite models

Andrew J. P. Garner

摘要:

计算的最小热成本受Landauer原理的限制。在这里,我得出有限建模的界限-生产或预期的模式(时间序列数据)-通过设备,以分段的方式模型的模式,并配备了有限的内存。当产生一个模式,我表明,最小耗散是成比例的信息在模型的内存中的模式的历史,从来没有体现在设备的未来行为,必须从内存中删除。我提供了一个模型的一般结构,允许这种耗散减少到零。通过考虑消耗或影响模式任意变化的设备,我讨论了这些有限模型如何形成符合热力学第二定律的信息库框架。

英文摘要:

The minimum heat cost of computation is subject to bounds arising from Landauer's principle. Here, I derive bounds on finite modelling -- the production or anticipation of patterns (time-series data) -- by devices that model the pattern in a piecewise manner and are equipped with a finite amount of memory. When producing a pattern, I show that the minimum dissipation is proportional to the information in the model's memory about the pattern's history that never manifests in the device's future behaviour and must be expunged from memory. I provide a general construction of model that allow this dissipation to be reduced to zero. By also considering devices that consume, or effect arbitrary changes on a pattern, I discuss how these finite models can form an information reservoir framework consistent with the second law of thermodynamics.
