We show that as the number of particles increases from 3 to 4, the behavior of QFI drastically changes. We also show how the dependence of QFI on the relative phase weakens as the number of particles increases. We also analyze the QFI for the state for several instances of N due to the change of the relative phases.eninfo:eu-repo/semantics/openAccessQuantum Fisher informationGHZ statesW statesHeisenberg limitArticleQ3Q253932193225WOS:000340615200034
