Can the double slit experiment distinguish between QM interpretations?

[QUOTE="PeterDonis, post: 6840669, member: 197831"] [B]TL;DR Summary:[/B] A paper just released on arxiv claims that the double slit experiment can be used to distinguish between QM interpretations. Is its claim correct? This paper claims that the double slit experiment can be used to distinguish between QM interpretations: [URL]https://arxiv.org/abs/2301.02641[/URL] IMO, the paper goes astray right at the start, when it points out that time is a parameter in the Schrodinger equation, not an operator, so that equation gives no way to uniquely derive a probability distribution for measurement results as a function of time--but then fails to note that the solution to that problem is to not use the Schrodinger equation in the first place. The correct framework in which to treat time on the same footing as other observables is relativistic quantum field theory. That is never even mentioned in this paper. To be fair, I have never seen *any* discussion or comparison of QM interpretations that uses QFT as its framework; they all use non-relativistic QM, even though we know that's just an approximation. But I think it's still an issue even if it's an extremely common one. What do other QM experts here think? [/QUOTE]
