Read Mermin who has written some popular papers on "The Ithaca Interpretation of Quantum
Mechanics", e.g. http://arxiv.org/pdf/quant-ph/9801057.pdf and the paper by Adami and
Cerf, which is where Garrett gets his talk, arxiv.org/pdf/quant-ph/0405005/?/
They take an information theoric approach to the quantum measurement problem and show that
a measurement can only get you part of the information in the quantum state. From the MWI
standpoint this 'other information' is in the other world branch. Mermin and Adami and
also Fuchs (http://arxiv.org/pdf/1003.5209.pdf) take a more instrumentalist approach in
which your conscious perceptions are fundamental and QM is a way to compute their
relations. The wave-function is just a summary representation of your knowledge of the
system. That's why he refers to it as the zero-worlds interpretation; it's all in your
(our) mind.

It's a bit long, but I'd be interested to hear anyone's thoughts who is knowledgeable on
QM. I don't follow the maths, but I kind of got the gist. What intrigued me was his
interpretation of QM and I'm wondering if anyone can throw any more light on it. He
makes a lot of jumps which are obviously clear in his mind but hard to follow. He says
that MWI is supportable by the maths, but that he prefers a "zero universes"
interpretation, according to which we are classical simulations in a quantum computer.
I'm not sure I follow this. I mean, I can follow the idea of being a classical
simulation in a quantum computer, but I can't see how this is different from MWI, except
by the manoeuvre of declaring other universes to be unreal because they can never
practically interact with 'our' branch. I guess what interested me was the possibility
of a coherent alternative to MWI (because frankly MWI scares the willies out of me), but
in spite of what he said, I couldn't see what it was...
