False dichotomy.  There are other ways to explain it.

When you drop a ball into a funnel, the exit of which is pointed down,
does the ball "actually" fall in all the ways other than through the
funnel's exit?  No, it does not - unless the ball's atoms all
quantum-teleport through the funnel's wall, an event so unlikely that
it has yet to happen once in the universe - and no multiverse is
needed to explain this.  Likewise in a quantum computer, the answer
that comes out was so very likely (though this might only be formally
provable in hindsight, with much more computation time than the
quantum computer needed) that it's the only one that comes out.
