TECH: Quantum Head JobI wonder what is the interpretation of entangled particles
in the multiverse QM. <snip> This would seem to be just as
effective in precluding instantaneous communication as the
classical interpretation.
Rafal Smigrodzki, MD-PhD


Instantaneous influences and instantaneous communications are, in some
sense, non-local. The MWI is, in another sense, non-local itself. But interferences
between different worlds are possible (according to many authors).

  Quantum nonlocality may be an artifact of the assumption that observers obey the laws of classical mechanics, while observed systems obey quantum mechanics. I show that, at least in the case of Bell's Theorem, locality is restored if observed and observer are both assumed to obey quantum mechanics, as in the Many-Worlds Interpretation. Using the MWI, I shall show that the apparently "non-local" expectation value for the product of the spins of two widely separated particles --- the "quantum" part of Bell's Theorem --- is really due to a series of three purely local measurements. Thus, experiments confirming "nonlocality" are actually confirming the MWI.
