重新审视量子语境

Revisiting Quantum Contextuality

Philippe Grangier

摘要:

本文的目的是完成最近出现的关于量子语境性的有趣评论[1]。特别是,我们将介绍和讨论的想法extradcontextuality和extravalence,让一个有关Kochen-Specker的和格里森的定理,也转移重点从第一个到第二个。我们还将论证,虽然Kochen-Specker的基本上是一个否定的结果(一个不通过定理),但Gleason的是一个肯定的结果,因为它提供了玻恩规则的数学证明。这些问题之间的联系是由一个特定的量子特征提供的,我们称之为额外性。

英文摘要:

The purpose of this note is to complete the interesting review on quantum contextuality [1] that appeared recently. In particular we will introduce and discuss the ideas of extracontextuality and extravalence, that allow one to relate Kochen-Specker's and Gleason's theorems, and also to shift the emphasis from the first to the second one. We will also argue that whereas Kochen-Specker's is essentially a negative result (a no-go theorem), Gleason's is a positive one since it provides a mathematical justification of Born's rule. The link between these issues is provided by a specific quantum feature that we call extravalence.
