Superpositions and complex structures

[Billmyk]

So I get that when starting at Eigenstate A all super-positions wave functions are collapsed do to entanglement with "observed eigenstate A.
My theoretical question is since sub-atomic particles are entangled in there "eigenstate" space-time positions, wouldn't that mean that complex structures of sub atomic particles such as matter that contain quarks, strong force, gluons, ect...would also be entangled in" the there super-position(s) as well, making up the same complex structures in there other eigenstate superposition(s) in theory ?

You can treat non-elementary particles like protons like elementary particles if the energies are low enough. If the energy is high enough, you have to consider the constituents individually, and you get a multi-particle system (which still follows the laws of quantum mechanics, of course, but is is much more complex).

So I get that when starting at Eigenstate A all super-positions wave functions are collapsed do to entanglement with "observed eigenstate A.

Collapse means no entanglement any more.

There are no "eigenstate space-time positions".

Ok, thanks

I understand what your saying, I thought if entanglement ends at wave collapse in a complex structure of particles strong force is holding them together so they remain in a structured state. At the super positions but decohersed

I don't understand that post.
