具有少量可观测量的上下文性

Contextuality with a Small Number of Observables

Frédéric Holweck, Metod Saniga

摘要:

我们调查小的几何配置,提供可观的基于证据的Kochen-Specker定理。假设每个上下文由相同数量的观测值和每个观测值是由两个上下文共享,它被证明是最经济的证明是著名的Mermin佩雷斯广场和Mermin五角星功能,分别为$9$和$10$观测值,有没有证据使用小于$9$观测值。我们还提出了一个新的证明与$14$可观的形成一个“魔术”七角形。另一方面,其他一些突出的小尺寸有限的几何形状,如Pasch配置和棱镜,被证明是不上下文。

英文摘要:

We investigate small geometric configurations that furnish observable-based proofs of the Kochen-Specker theorem. Assuming that each context consists of the same number of observables and each observable is shared by two contexts, it is proved that the most economical proofs are the famous Mermin-Peres square and the Mermin pentagram featuring, respectively, $9$ and $10$ observables, there being no proofs using less than $9$ observables. We also propose a new proof with $14$ observables forming a `magic' heptagram. On the other hand, some other prominent small-size finite geometries, like the Pasch configuration and the prism, are shown not to be contextual.
