量子理论最小模态解释中的测量与量子动力学

Measurement and Quantum Dynamics in the Minimal Modal Interpretation of Quantum Theory

Jacob A. Barandes, David Kagan

摘要:

任何对量子理论的实在论解释都必须解决测量问题和态矢量坍缩的状况。在无塌陷方法中,测量通常被建模为涉及退相干的动态过程。我们描述了如何最小模态解释关闭在这个动态描述的差距,导致一个完整的和一致的解决方案的测量问题和有效形式的状态崩溃。我们的解释还提供了对测量的不可分割性的洞察-事实上,你不能停止测量的中途,并揭示潜在的“本体”的动态系统的问题。在讨论了测量过程中系统的本体状态的隐藏动态之后,我们转向更一般形式的开放系统动态,并探索系统的潜在本体行为的细节可以描述的程度。我们构造了一个本体轨迹空间,并描述了障碍物,以定义在这个空间上的概率测度。

英文摘要:

Any realist interpretation of quantum theory must grapple with the measurement problem and the status of state-vector collapse. In a no-collapse approach, measurement is typically modeled as a dynamical process involving decoherence. We describe how the minimal modal interpretation closes a gap in this dynamical description, leading to a complete and consistent resolution to the measurement problem and an effective form of state collapse. Our interpretation also provides insight into the indivisible nature of measurement--the fact that you can't stop a measurement part-way through and uncover the underlying `ontic' dynamics of the system in question. Having discussed the hidden dynamics of a system's ontic state during measurement, we turn to more general forms of open-system dynamics and explore the extent to which the details of the underlying ontic behavior of a system can be described. We construct a space of ontic trajectories and describe obstructions to defining a probability measure on this space.
