我们为非专家回顾了(理论)物理和信息之间的界面。首先在热力学的背景下,然后在统计力学的背景下,描述了与熵概念有关的信息的起源。对统计力学基础的仔细研究和调和世界的概率和确定性观点的需要导致我们讨论混沌动力学,在混沌动力学中,信息在量化可预测性方面发挥着至关重要的作用。然后,我们讨论在定义信息时出现的各种基本问题,以及在讨论有序、无序和不完全知识等概念时必须如何谨慎。我们还讨论了熵的另一种形式及其与非平衡态热力学的可能相关性。在论文的最后一部分,我们讨论了量子力学是如何产生与此截然不同的量子信息概念的。由于量子力学中固有的大规模并行处理,信息存储和计算有了全新的可能性。我们还指出如何将熵扩展到量子力学中,为量子纠缠提供一种有用的测量方法。最后,我们对量子理论和广义相对论之间的界面作了一个小的探索,在那里我们面临着黑洞物理提出的“终极信息悖论”。在这次审查中,我们限制了自己;并不是所有涉及物理和信息的相关主题都可以涵盖。

英文摘要:
  We review of the interface between (theoretical) physics and information for non-experts. The origin of information as related to the notion of entropy is described, first in the context of thermodynamics then in the context of statistical mechanics. A close examination of the foundations of statistical mechanics and the need to reconcile the probabilistic and deterministic views of the world leads us to a discussion of chaotic dynamics, where information plays a crucial role in quantifying predictability. We then discuss a variety of fundamental issues that emerge in defining information and how one must exercise care in discussing concepts such as order, disorder, and incomplete knowledge. We also discuss an alternative form of entropy and its possible relevance for nonequilibrium thermodynamics.   In the final part of the paper we discuss how quantum mechanics gives rise to the very different concept of quantum information. Entirely new possibilities for information storage and computation are possible due to the massive parallel processing inherent in quantum mechanics. We also point out how entropy can be extended to apply to quantum mechanics to provide a useful measurement for quantum entanglement.   Finally we make a small excursion to the interface betweeen quantum theory and general relativity, where one is confronted with an "ultimate information paradox" posed by the physics of Black Holes.   In this review we have limited ourselves; not all relevant topics that touch on physics and information could be covered.
