Quantum Mechanics would be refuted (with or without wave packet
reduction).
thus making QM a deterministic theory,
You mean QM+collapse. With QM-without-collapse: QM is determinist in
the third person picture, and non determinist from the perspective of
the most observers.
would that imply an INCONSISTENCY in the postulates of QM? TIA.
Yes. If QM with collapse becomes deterministic, I think this would be
close to adding local hidden variable, which are refuted by EPR/Bell.
Ah, I see Brent wrote
It would make it possible to use EPR like experiments to send
signals faster than light...which is to say backward in time. That
would pretty much screw up all known physics...and common sense.
Yes, I agree. QM+collapse+SP would be close to nonsense.
I agree with all what brent say, so I don't need to add anything. The
measurement problem is quasi conceptually solved by decoherence in QM
without collapse, although not entirely when we take into account
Mechanism !
But the measurement problem is a "physical problem" if you assume the
wave packet reduction, and the problem consists in making sense of it,
in a way having testable consequence, and an as clear as possible
interpretation of the wave(s) or the (density) matrix. It is not a
problem for the applications. Measurement is indeed a powerful gate in
quantum computing. The measurement problem is mainly the
interpretation problem of the wave/matrix, to make sense of a notion
of "physical reality".
It is also a good introduction of the mind body problem. Digital
Mechanism generalizes it to arithmetic, and where the wave/matrix
itself has to be justified from the reality about the numbers semi-
computable relations verified in Arithmetic.
