Hi guys,
as it has been said many times on the forum and outside of it the ability to achieve and maintain coherence is the biggest reason why macroscopic superpositions cannot be measured. The typical examples of macroscopic coherence are superconductors where atoms all behave in a similar fashion, therefore bringing coherence from the micro level to the macro level. So my question is, do the atoms in macro objects, or should I say it better - in systems of many, many particles have to behave in a similar way, non-independently to achieve coherence of the system as a whole and therefore creating a superposition of two distinct quantum states of the system as a whole? In the fictive and so oftenly mentioned Schrodinger's cat, would all the atoms inside of the cat's body act coherently like in the case of a superconductor while 'giving us' the alive and dead states?
I appreciate your help. Regards.
