That paper by Albert use the FPI, or a quantum FPI-like notion, and is  
close to Everett's view. Yet, if I remember correctly, Albert, who  
criticized the Many-World a lot in his book "QM and experiences" has  
restated his self-theory in a Bohmian frame (with still sort of  
parallel universe (as Deutsch argues correctly (I think), and lacking  
particles and full of p-zombies). I found that development very weird,  
and it cannot be used with digital mechanism (even with a quantum  
automata). So Albert was close, but then drifted away ...


I will look at Peres paper, but usually I am not very convinced by its  
metaphysical assumption, even without assuming computationalism.  I  
will comment if I find that I missed something.

The physics relies on is acknowledged, on not, D. Deutsch @Oxford). Quantum 
computers branching calculations to other universes was Deutsches' bailiwick.

I don't know multiple universes, or just one frick'in big one? This one is 
looking dead as a doornail round these parts.

Subject: QM Automata

Here are a couple of papers that may be of interest.  Albert considers 
what a QM automata may know about itself and arrives at some unexpected 
result.  Peres throws some cold water on the result - but Peres doesn't 
believe in a multiverse.
