BruMa:
I disagree: in Bohm QM there *are* other branches. This follows
from the fact that there is no collapse. The SWE is obeyed.
Bohm just add a potential which forces a (mysterious) set
of particles with very special initial conditions to follow
one branch of the universal superpositions. But to explain
the interference Bohm accepts the existence of the other branches
even if they are lacking particles. And to explain the behavior
of a quantum computer even in just "our" branch, a Bohmian must
accept that the computers of the other branches are able to make
reasoning like any AI, even if they lacks particles. So Bohm
is forced to abandon comp, as he does. (This illustrates also that
existence of particles is hardly necessary with comp).
