What primarily interests me is whether S's superpostion of |alive> and

Which is exactly what the reference I cited addresses.

TY. I'll study it carefully. AG 

It looks like a real heavy lift. Not sure I am up to it, but I'll try. AG 


At start of 2nd paragraph of section 4.2, it says "In our scheme quantum 
states are just assignments of probabilities to possible events, that is, 
possible measurement outcomes." But superpositions are characterized by the 
system being represented, being in all states of the superposition 
simultaneously before measurement. From this, in the case of S's cat. we 
get a cat Alive and Dead simultaneously before the box is opened. But, by 
virtue of quote, isn't the author defining away the problem to be solved 
for S's cat? TY, AG

The question boils down to this; if there's no operator which has those 
values as eigenvalues, is it legimate to construct a "superposition" of 
those eigenvalues and conclude anything about QM?  AG
