贝尔不等式与不相容测量

Bell inequalities and incompatible measurements

Peter Morgan

摘要:

贝尔不等式是测量不相容性的结果(而不是像通常认为的那样是非定域性的结果)。用经典的术语来说,这相当于情境性--测量设备确实有显著的影响。上下文模型在经典物理学中是合理的,它总是认为我们尽可能忽略测量设备,但如果这还不够好,那么我们必须对测量设备进行建模。也有人认为,量子理论只应采取反事实的严重性,因为测量不相容是一个反事实的概念。

英文摘要:

Bell inequalities are a consequence of measurement incompatibility (not, as generally thought, of nonlocality). In classical terms, this is equivalent to contextuality -- measurement devices do have a significant effect. Contextual models are reasonable in classical physics, which always took the view that we ignore measurement devices whenever possible, but if that isn't good enough then we do have to model measurement devices. It is also argued that quantum theory should only be taken with counterfactual seriousness, because measurement incompatibility is a counterfactual concept.
