论文摘要
熵铃不平等见证了可观察到的共同测量值的上下文概率分布。我们发现，它们的违规并不需要违反某些参数值的相关铃不平等。熵和相关度量之间的这种异常，有助于精确限定非古典资源的类型。我们确定其数值界限，邀请他们的实验验证。在保持这种异常现象的可观察物的排列中，我们确定了在所有无等于的操作方下在设备无关的方法下引起非古典资源的“异国”类型。
Entropic Bell inequalities witness contextual probability distributions on sets of jointly measurable observables. We find that their violation does not entail a violation of the correlative Bell inequality for certain parameter values. This anomaly between the entropic and correlative measures of contextuality helps to precisely qualify the type of non-classical resource. We determine its numerical bounds inviting their experimental verification. Among the permutations of observables that keep this anomaly in place, we identify the 'exotic' type that gives rise to non-classical resources under all non-equivalent operational party assignments in a device-independent approach.
