摘要

波恩规则的内容和表述的细节从1926年波恩开始到现在已经发生了很大的变化。本文追溯了100年前玻恩规则的早期历史，它在大约50年前的推广（对今天的量子光学和量子信息理论至关重要）到povm，以及量子探测器概念的直观定义的现代推导。还讨论了玻恩定则的各种形式在多大程度上，像物理学中的任何其他陈述一样，具有有限的有效性领域，这在应用于该领域之外时会导致问题。

The Born Rule-100 Years Ago and Today.

The details of the contents and formulations of the Born rule have changed considerably from its inception by Born in 1926 to the present day. This paper traces the early history of the Born rule 100 years ago, its generalization (essential for today's quantum optics and quantum information theory) to POVMs around 50 years ago, and a modern derivation from an intuitive definition of the notion of a quantum detector. Also discussed is the extent to which the various forms of the Born rule have, like any other statement in physics, a restricted domain of validity, which leads to problems when applied outside this domain.

期刊介绍： Entropy (ISSN 1099-4300), an international and interdisciplinary journal of entropy and information studies, publishes reviews, regular research papers and short notes. Our aim is to encourage scientists to publish as much as possible their theoretical and experimental details. There is no restriction on the length of the papers. If there are computation and the experiment, the details must be provided so that the results can be reproduced.
