Deutsch claims in the article to have proved that any physical process can in principle be emulated at arbitrarily fine detail by a universal quantum Turing machine. Is this proof widely accepted? I tried to read the paper, but the math is beyond me. I’ve found relatively little discussion of it elsewhere, and most of it critical.

I’d say this falls under the Church-Turing thesis.
In his 1985 paper he seems to be arguing that he uniquely extends the Church-Turing thesis.
