论文摘要
准备和量学理论是一种新型的量子悖论，它揭示了经典理论和量子力学之间的不相容性，从物理系统的维度来看。正如Horodecki标准一样，可以确定能够表现出钟声非阶级的量子状态，是否能够表现出相似的标准，以确定准备和分配的状态是否能够进行准备，以确定是否可以进行准备。最近，Poderini等。 [物理。 Rev. Research 2，043106（2020）]提出了用于准备和衡量非古老性的标准。在这项工作中，我们通过实验验证了该标准 - 使用此标准，准备了52组不同的量子状态，并一一对一一进行测试，以确定它们是否可以表现出准备和测量非经典性，并且实验结果与理论期望非常吻合。在此处经过实验验证的标准有可能在未来关于准备和衡量非古老性的研究中广泛使用。
The prepare-and-measure theory is a new type of quantum paradox that reveals the incompatibility between classical theory and quantum mechanics in terms of the dimensionality of physical systems.Just as the Horodecki criterion can determine whether given quantum states are capable of exhibiting Bell nonclassicality, a similar criterion is needed for the prepare-and-measure theory to determine whether given uantum states can exhibit the prepare-and-measure nonclassicality. Recently, Poderini et al. [Phys. Rev. Research 2, 043106 (2020)] presented such a criterion for the prepare-and-measure nonclassicality. In this work, we experimentally validate this criterion -- 52 different sets of quantum states are prepared and tested one by one using this criterion to determine whether they can exhibit the prepare-and-measure nonclassicality, and the experimental results are in good agreement with the theoretical expectations. The criterion experimentally verified here has the potential to be widely used in future research on the prepare-and-measure nonclassicality.
