量子情境性的实验测试证明或反驳了什么?

What does an experimental test of quantum contextuality prove or disprove?

Andreas Winter

摘要:

在Meyer、Kent和Clifton-Kent证明量子力学的预言与非上下文模型的预言无法区分(达到任意精度)之后,以及随后的辩论这些模型在多大程度上实际上是经典的或非上下文的之后,对贝尔-科亨-斯佩克定理进行了实验检验的可能性进行了严格的研究。本分析从仔细考虑这些“有限精度”近似开始。一个更强的条件,非上下文模型,被称为<ontological faithfulness>,展出。它表明,它允许制定近似的约束,贝尔-Kochen-Specker定理,如使通常的证明稳健。因此,人们可以通过实验来测试有限精度的本体论忠实的非语境性,从而通过实验来反驳这个较小类别的解释。我们包括本体论的忠实性的关系,以克服有限的精度反对其他建议的讨论。

英文摘要:

The possibility to test experimentally the Bell-Kochen-Specker theorem is investigated critically, following the demonstrations by Meyer, Kent and Clifton-Kent that the predictions of quantum mechanics are indistinguishable (up to arbitrary precision) from those of a non-contextual model, and the subsequent debate to which extent these models are actually classical or non-contextual. The present analysis starts from a careful consideration these "finite-precision" approximations. A stronger condition for non-contextual models, dubbed <ontological faithfulness>, is exhibited. It is shown that it allows to formulate approximately the constraints in Bell-Kochen-Specker theorems such as to render the usual proofs robust. As a consequence, one can experimentally test to finite precision ontologically faithful non-contextuality, and thus experimentally refute explanations from this smaller class. We include a discussion of the relation of ontological faithfulness to other proposals to overcome the finite precision objection.
