If they managed to make quantum calculations does it mean that it validates the many worlds/multiverse theory?

  no

    To expand a bit on this quite correct "no": There are many interpretations of quantum mechanics, like Bohm Mechanics, Multiverse, Copenhagen, but they all are mathematically equivalent and indistinguishable. They are of purely philosophical interest, not scientific (people will argue about this last sentence, but this would be an argument over semantics, not science). So please do not call it "Multiverse theory", rather "Multiverse interpretation" :)

      Uh, no. MWI and Copenhagen make different predictions. It just requires a reversible quantum computer to test. It is possible to distinguish which is true but it may take a few generations of experiment.

        Could you elaborate on that? I have hard time believing it without a reference. Edit: Probably you were referring to the need for "wavefunction collapse" in the Copenhagen theory. Practically, this can be addressed with the Master equations (or other approaches) for open quantum systems. Philosophically it might be unpleasant, but mathematically it is no different from what the Many World/Multiverse requires.
