QM的非上下文重新解释的可观测量和状态的扩展表示

Extended Representations of Observables and States for a Noncontextual Reinterpretation of QM

Claudio Garola, Sandro Sozzo

摘要:

性质的非客观性是量子力学的一个重要而又成问题的特征。ESR模型恢复了客观性,将量子概率重新解释为以检测为条件,并将QM的数学形式体现为更广泛的非上下文(因此是局部)框架。我们在这里提出了一个改进的介绍ESR模型包含一个更完整的数学表示模型的基本实体。我们还将该模型扩展到混合物,表明适当的混合物的数学表示不符合QM提供的混合物的数学表示,而不适当的混合物的表示。ESR模型的这一特点使得在处理混合物时避免了QM中出现的一些解释性问题。从经验的角度来看,ESR模型的预测取决于一些参数,这些参数在大多数情况下可能非常接近QM的预测。但是,适当的混合物的非标准表示允许我们提出一个实验方案,可以检查是否QM的预测或ESR模型的预测是正确的。

英文摘要:

A crucial and problematical feature of quantum mechanics (QM) is nonobjectivity of properties. The ESR model restores objectivity reinterpreting quantum probabilities as conditional on detection and embodying the mathematical formalism of QM into a broader noncontextual (hence local) framework. We propose here an improved presentation of the ESR model containing a more complete mathematical representation of the basic entities of the model. We also extend the model to mixtures showing that the mathematical representations of proper mixtures does not coincide with the mathematical representation of mixtures provided by QM, while the representation of improper mixtures does. This feature of the ESR model entails that some interpretative problems raising in QM when dealing with mixtures are avoided. From an empirical point of view the predictions of the ESR model depend on some parameters which may be such that they are very close to the predictions of QM in most cases. But the nonstandard representation of proper mixtures allows us to propose the scheme of an experiment that could check whether the predictions of QM or the predictions of the ESR model are correct.
