作为真系综的波函数

The wavefunction as a true ensemble

Jonte R. Hance, Sabine Hossenfelder

摘要:

在量子力学中,波函数预测可能的测量结果的概率,但不是在每次实验中实现的单个结果。这表明它描述了一个具有不同隐变量值的状态系综。在这里,我们分析这个想法与目前已知的定理和实验。我们认为,$ψ$ -本体/认知的区别不能正确识别合奏的解释,并提出了一个更有用的定义。然后,我们表明,所有的本地$ψ$系综解释再现量子力学违反统计独立性。具有这种性质的理论通常被称为超决定论或追溯因果论。最后,我们解释了这种解释如何帮助理解量子力学中的一些令人困惑的现象,如延迟选择实验,埃利祖尔-魏德曼炸弹探测器和扩展的维格纳之友场景。

英文摘要:

In quantum mechanics, the wavefunction predicts probabilities of possible measurement outcomes, but not which individual outcome is realised in each run of an experiment. This suggests that it describes an ensemble of states with different values of a hidden variable. Here, we analyse this idea with reference to currently known theorems and experiments. We argue that the $ψ$-ontic/epistemic distinction fails to properly identify ensemble interpretations and propose a more useful definition. We then show that all local $ψ$-ensemble interpretations which reproduce quantum mechanics violate Statistical Independence. Theories with this property are commonly referred to as superdeterministic or retrocausal. Finally, we explain how this interpretation helps make sense of some otherwise puzzling phenomena in quantum mechanics, such as the delayed choice experiment, the Elitzur-Vaidman bomb detector, and the Extended Wigner's Friends Scenario.
