> Wave functions are just a mathematical representation of a physical property that are (only?) ever operated on using quantum operators which result in a statistical distribution. It is not correct— at least not unless you subscribe to the Copenhagen interpretation. Yet, while this interpretation is a simple heuristic for interaction with big systems (e.g., a photon hits a CCD array), none of the quantum physicists I know treat it seriously (for that matter, I have a PhD in quantum optics theory). I mean, at some certain level, everything is "just a mathematical representation" - in the…

This view on wave-particle duality and the quantum measurement is a (very) leaky abstraction. It is a process, governed by decoherence - for a nice overview, see e.g. "Decoherence, einselection, and the quantum origins of the classical" by Zurek (https://arxiv.org/abs/quant-ph/0105127).
