Is a universal quantum computer expected to be able to shed any light on the measurement problem? - Part B



Following up on Part A.



Suppose we build a universal quantum computer and it functions as we currently expect it to. Is there any reason to suggest that, beyond its uses for things like cryptography and quantum system simulation, such a device could be used to shed light on the measurement problem?



Specifically:




  • All of the mainstream interpretations of QM return the same predicted results, but differ in their explanations 'why'. Can a universal quantum computer be given problems to solve whose answers would distinguish between these interpretations?





  • If a universal quantum computer can be built, and functions properly, is that in and of itself evidence in favor of/against any interpretation(s)?




  • Would the failure of a universal quantum computer to resolve this question be considered a serious 'blow' to resolving the measurement problem in general?




N.B.1. I know that there is a position that a working quantum computer may be evidence of, or against, certain interpretations, such as here, here and here, but from what I can see that position is not entirely resolved, so I wanted to ask the question 'neutrally' so as to encompass all of the interpretations.


(As before, I used a universal quantum computer in my question, but if another kind of quantum computation device is more appropriate or preferred, then please tell me/answer in that spirit.)
