状态无关上下文性的最小证明

Minimal proofs of state-independent contextuality

Adan Cabello

摘要:

最近的研究表明,状态无关的上下文(SIC)是一个基本的资源与一种类型的非局部性,不能改善非信令资源。因此,确定证明SIC所需的最简单的量子可观测量集是至关重要的。我们表明,d+10秩-1投影机是足够的,以证明SIC的任何物理系统在D>2的尺寸。这个结果优于最好的Kochen-Specker证明和Yu和Oh在arXiv:1112.5513v1中提出的结果。

英文摘要:

It has been recently shown that state-independent contextuality (SIC) is a fundamental resource linked with a type of nonlocality which cannot be improved by nonsignaling resources. Therefore, it is of fundamental importance to identify the simplest sets of quantum observables needed to prove SIC. We show that d+10 rank-1 projectors are sufficient to prove SIC for any physical system in dimension d>2. This result outperforms both the best Kochen-Specker proofs and the results presented by Yu and Oh in arXiv:1112.5513v1.
