论文摘要
本说明的目的是完成有关最近出现的量子上下文性[1]的有趣评论。特别是我们将介绍和讨论外观和奢侈的思想，这使人们可以将Kochen-Specker和Gleason的定理联系起来，并将重点从第一个转移到第二个。我们还将争辩说，尽管Kochen-Specker的本质上是一个负面结果（无关定理），但格里森是一个积极的结果，因为它提供了对Born统治的数学合理性。这些问题之间的链接由我们称为奢侈的特定量子功能提供。
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.
