It is elementary quantum computing. You can take just Deutsch problem, or Deutsch Josza problem. Deutsch “invented” that problem to show that the many-worlds are testable. Of course, that can give only an indication, and if we assume QM is correct, that is not much more than the two slits. QM without collapse is the same as the many-worlds. Superpositions just never disappear when there is no collapse.
