标题： Testing noncontextuality inequalities that are building blocks of quantum correlations

摘要： 包含由五边形、七边形、九边形等及其补集表示的排斥关系事件的测量场景，是唯一无法用经典概率描述的场景。 有趣的是，量子理论预测，这些图中的任何图的最大值都无法在贝尔不等式场景中实现。 除了五边形之外，这一预测尚未经过实验验证。 在这里，我们分别使用三维和五维量子态对七边形及其补集的量子最大值进行测试。 在两种情况下，我们采用两种不同的编码方式：单光子的线性横向动量和轨道角动量。 我们的结果排除了最大非上下文相关隐变量理论，并与量子理论预测的最大值良好一致。 显示英文摘要

摘要： Measurement scenarios containing events with relations of exclusivity represented by pentagons, heptagons, nonagons, etc., or their complements are the only ones in which quantum probabilities cannot be described classically. Interestingly, quantum theory predicts that the maximum values for any of these graphs cannot be achieved in Bell inequality scenarios. With the exception of the pentagon, this prediction remained experimentally unexplored. Here we test the quantum maxima for the heptagon and the complement of the heptagon using three- and five-dimensional quantum states, respectively. In both cases, we adopt two different encodings: linear transverse momentum and orbital angular momentum of single photons. Our results exclude maximally noncontextual hidden-variable theories and are in good agreement with the maxima predicted by quantum theory.
