roughly like a coin toss where there is no interference.
Generalizing interference to every quantum state is where
Schrodinger went wrong. The cat, which shares or inherits the wf

simultaneously. AG
In the double slit, the paths through the two slits remain
coherent, so they can interfere when they come together. In the
case of nuclear decay, the coherence is lost immediately, so the
nucleus does not interfere with the decay products.

So you agree or disagree with my conclusion; namely, the cat is
never in a superposition of states? That is, no situation where cat
is Alive and Dead simultaneously. I think you disagree and think
the nuclear state is superposed with interference existing. AG
The superposition of |live + dead> or |live - dead> does not exist
in any single world since such states are not stable against
decoherence. But if you take the pedantic view of the many worlds of
MWI, the superposition of live and dead cats, together with
everything entangled with them, exists for ever in the
multiverse. What good that does anyone, I fail to understand.
Searching the good and searching the truth might be different thing,
unless you add the quite platonic axiom that truth is good, which I
hope, but that is hardly usable in a reasoning.
