AI总结:

本文探讨多世界解释如何通过原子干涉仪中测路径的波色计探测器模型,展示微观物体、测量设备和观察者在同一框架下的一致性,并讨论其与实验观测的匹配性及无超距作用的特点。

摘要:

多世界解释(MWI)对量子力学提出了一个简单的问题:如果一切按照相同的量子方程演化,现实会是什么样?将微观物体、测量设备和观察者置于同一框架下具有吸引力,但预测是否符合观测?本文构建了一个在原子干涉仪中进行路径测量的波色计探测器模型。我们讨论了MWI的主张,即在每次实验迭代中,两种测量结果都会发生,但观察者将经历其中一种结果,其概率与实验一致。最后,我们讨论了MWI如何不具有超距作用。本文旨在为具有量子力学本科课程背景的读者提供可理解的内容。

英文摘要:

The many-worlds interpretation (MWI) of quantum mechanics poses a simple question. What would reality look like if everything evolved in time according to the same quantum equations? There is an attractive consistency to treating microscopic objects, measuring devices, and observers all on the same footing, but do the predictions match our observations? Here, we build a model for a bolometer detector making a which-path measurement in an atom interferometer. We discuss the MWI claim that, while both measurement outcomes occur in each experimental iteration, an observer will experience only one outcome or the other, with a probability consistent with experiment. Finally, we discuss how MWI does not have action at a distance. This article is written to be accessible to anyone with an undergraduate course in quantum mechanics.
