Does the Frauchiger-Renner Theorem prove only MWI is correct

  • #1
Hello all, I have only seen this paper brought up here once before based on the search function 2 years ago, and the thread devolved into something off topic within the first page.

I am asking in reference to this paper:

https://arxiv.org/pdf/1604.07422.pdf

Which claims to show that single world interpretations of quantum mechanics are not consistent.

I was wondering if any of you here have gone over this paper, or would like to give you thoughts on it, and it's usage by MWI proponents of this paper proving that Many Worlds is the only correct interpretation.

Thanks in advance for any and all comments.

So from what I can gather with my introductory understanding of QM, the paper makes an unfounded assumption about new measurements deleting information about the outcomes of previous measurements, and something about Hardy's Paradox that my understanding and math is not quite to par to understand?
Roughly, yes.

Roughly, yes.
Nice, thanks for the quick replies. Off topic question and prob my final post, but what interpretation do you personally prefer, I know they are all experimentally the same, but do you have a personal preference or one your intuition tells you might be more correct?
