- Abstract: Entanglement potentials are a promising method for the characterization of
quantum state nonclassicality. Although they possess several interesting
benefits, they critically rely on a well-tailored interaction between the
tested state and a suitable classical state. We analyze the effect of
imperfections in the interaction that are in real experiments to some extent
always unavoidable. Furthermore, we study hierarchies of several entanglement
potentials allowing us to detect these imperfections and, thus, preventing from
misjudging the true intrinsic nonclassicality of the investigated states. The
proposed idea is demonstrated in a proof-of-principle experiment on the
platform of linear optics.

Three notions are often assumed to be essentially equivalent, representing different facets of the same phenomenon.
We analyze them in general Friedmann-Lemaitre- Robertson-Walker space-times through the lens of geometric structures on the classical phase space.
The analysis shows that: (i) inflation does not play an essential role; classical behavior can emerge much more generally; (ii) the three notions are conceptually distinct; classicality can emerge in one sense but not in another.
