- Abstract: We evaluate the entanglement wedge cross section (EWCS) in asymptotically AdS
geometries which are dual to boundary excited states. We carry out a
perturbative analysis for calculating EWCS between the vacuum and other states
for a symmetric configuration consisting of two disjoint strips and obtain
analytical results in the specific regimes of the parameter space. In
particular, when the states described by purely gravitational excitations in
the bulk we find that the leading correction to EWCS is negative and hence the
correlation between the boundary subregions decreases. We also study other
types of excitations upon adding the extra matter fields including current and
scalar condensate. Our study reveals some generic properties of boundary
information measures dual to EWCS, e.g., entanglement of purification,
logarithmic negativity and reflected entropy. Finally, we discuss how these
results are consistent with the behavior of other correlation measures
including the holographic mutual information.

We propose two schemes for generating Wigner-negative entangled states unconditionally in mechanical resonators.
We show analytically that both schemes stabilize a Wigner-negative entangled state that combines the entanglement of a two-mode squeezed vacuum with a cubic nonlinearity.
We then perform extensive numerical simulations to test the robustness of Wigner-negative entanglement attained by approximate CPE states stabilized in the presence of thermal decoherence.

We compute the geometric phases acquired in both unitary and dissipative Jaynes-Cummings models.
In the dissipative model, the non-unitary effects arise from the outflow of photons through the cavity walls.
We show the geometric phase is robust, exhibiting a vanishing correction under a non-unitary evolution.
