While I agree with the suggestion that MWI is no more preposterous that many of the non-intuitive properties of QM, the fact that it cannot be tested one way or the other makes it difficult for me to accept it. It's not the same with say, duality of electron which is proved beyond any doubt by experiments. accepting MWI is as good as accepting any other equally non-intuitive interpretation that also cannot be proved.

I don't think lack of engagement on my part is the rate-limiting step here, though your mileage may vary.Douglas Natelsonhttps://www.blogger.com/profile/13340091255404229559noreply@blogger.comtag:blogger.com,1999:blog-13869903.post-67790243415322747212022-05-04T12:01:17.005-05:002022-05-04T12:01:17.005-05:00"Perhaps there's a branch of the multiver..."Perhaps there's a branch of the multiverse where my readership is vast"<br />A prerequisite to vast readership is responding to, or otherwise interacting with, the people who post.Mayer Landaunoreply@blogger.comtag:blogger.com,1999:blog-13869903.post-19133927537587118282022-05-02T07:01:09.058-05:002022-05-02T07:01:09.058-05:00If one had a big enough quantum computer, could on...If one had a big enough quantum computer, could one "solve" the measurement problem? For example, by simulating the coupling of a few qubits to a bath of qubits. I have always held the interpretation (maybe wrongly) that all time evolution for the system and environment is given by a very complex, but still unitary, Schrodinger time evolution.
