论文摘要
我们能听到波功能崩溃的流行声，如果是，听起来会是什么样？存在量子力学（崩溃模型）的重建或修改，其中存在这种原型随机性的特征，可以原则上见证。但是，也许令人惊讶的是，由此产生的声音令人失望地平庸，与其他任何点击都无法区分。在两个完全不同的模型之间找到正确的世界描述的问题 - 波函数跳跃而它们不在的地方 - 在经验上是不可证实的。这种看似琐碎的观察背后是关于量子力学的刚性，难以将不可预测性归咎于内在随机性的难度以及更普遍地对我们对现实知识的物理局限性的深入的教训。
Could we hear the pop of a wave-function collapse, and if so, what would it sound like? There exist reconstructions or modifications of quantum mechanics (collapse models) where this archetypal signature of randomness exists and can in principle be witnessed. But, perhaps surprisingly, the resulting sound is disappointingly banal, indistinguishable from any other click. The problem of finding the right description of the world between two completely different classes of models -- where wave functions jump and where they do not -- is empirically undecidable. Behind this seemingly trivial observation lie deep lessons about the rigidity of quantum mechanics, the difficulty to blame unpredictability on intrinsic randomness, and more generally the physical limitations to our knowledge of reality.
