- Abstract: We show that it is possible to still use semiclassical gravity together with
quantum field theory beyond the regimes where the field state is coherent. In
particular, we identify families of cat states (superposition of
almost-distinguishable coherent states that have very non-classical features)
for which the gravitational backreaction can be modeled by semiclassical
gravity.

Given a unitary evolution $U$, how well can $U$ be simulated by local operations and classical communication (LOCC) on that ensemble?
We establish a general, efficiently computable upper bound on the maximal LOCC simulation fidelity.
We then apply our findings to the fundamental setting where $U$ implements a quantum Newtonian Hamiltonian over a gravitationally interacting system.

We show that in the high-temperature regime, the classical result is recovered.

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.
