comment Is it possible to use the observation of wave function collapse as a basis for superluminal communication?
This is not an answer, just a replication of the OP's question, which moreover has been asked and answered many, many, many times on this site.

comment Average of $\sin^2 \omega t$, $\cos^2 \omega t$ for long times
Looks like the OP is trying to calculate the power spectrum of an oscillating classical dipole. @Programmer, it would be good if you could add this information into your question so it's more useful to other users of this site.

comment Average of $\sin^2 \omega t$, $\cos^2 \omega t$ for long times
Very nice complementary answer, +1. It's worth mentioning explicitly that the existence of a minimum temporal resolution/response time is the reason why measuring devices have a finite-bandwidth response in the frequency domain.

@KaziarafatAhmed The popular article you linked and the research it describes has nothing to do with many-worlds whatsoever!!

comment How to understand the entanglement in a lattice fermion system?
Good question. The issue of entanglement in fermionic Fock space has been studied in a number of works. As far as I know there is no unique definition of entanglement; see this nice review for more details. The map between the fermion and spin picture can be achieved using a Jordan-Wigner transformation, which is a bit more subtle than the simple idenfication you alluded to. When going between spin and fermion pictures, local operators get transformed to highly non-local operators in general.
