论文摘要
在这项工作中,我们试图面对量子力学基础文献(QM)中的正统广泛主张,根据“实验室中从未真正观察到的叠加”。为了做到这一点,我们首先提供对著名测量问题的批判性分析,我们将认为,这是由经验证明主义要求的严格应用以在其对“理论”的具体理解下汇总量子形式主义的严格应用。在这种情况下,可以将投影假设的临时引入(或测量规则)理解为从天真的经验主义者的角度来看的必要要求,该观察是观察是自我明显的“常识”经验的自我示威者 - 无独立的形而上学(分类(分类)预设。然后,我们将注意力转移到对QM的两个“非崩溃”解释(即模态和许多世界)上 - 尽管否认“崩溃”是一个真正的物理过程,无论如何,无论如何都将测量规则保留为理论的必要要素。在对立之后,按照爱因斯坦的主张,“只有决定可以观察到的理论”,我们建议回到现实主义的代表性理解对'物理理论'的理解,其中“观察”被认为是源自理论预设的。正是从这个角度来看,我们讨论了一种新的非古典概念表示形式,该表示使我们能够以直观的(anschaulicht)方式理解量子现象。留下投影假设,我们讨论了测量和观察量子叠加的一般物理条件。
In this work we attempt to confront the orthodox widespread claim present in the foundational literature of Quantum Mechanics (QM) according to which 'superpositions are never actually observed in the lab'. In order to do so, we begin by providing a critical analysis of the famous measurement problem which, we will argue, was originated by the strict application of the empirical-positivist requirements to subsume the quantum formalism under their specific understanding of 'theory'. In this context, the ad hoc introduction of the projection postulate (or measurement rule) can be understood as a necessary requirement coming from a naive empiricist standpoint which presupposes that observations are self evident givens of "common sense" experience --independent of metaphysical (categorical) presuppositions. We then turn our attention to two "non-collapse" interpretations of QM --namely, modal and many worlds-- which even though deny that the "collapse" is a real physical process anyhow retain the measurement rule as a necessary element of the theory. In contraposition, following Einstein's claim according to which "it is only the theory which decides what can be observed", we propose a return to the realist representational understanding of 'physical theories' in which 'observation' is considered as derived from theoretical presuppositions. It is from this standpoint that we discuss a new non-classical conceptual representation which allows us to understand quantum phenomena in an intuitive (anschaulicht) manner. Leaving behind the projection postulate, we discuss the general physical conditions for measuring and observing quantum superpositions.
