Abstract
We establish a Gaussian quantum-Langevin framework for steady-state entanglement in driven-dissipative polariton fluids with analog-gravity-inspired flow interfaces. Applying this to a 2D ring-pumped vortex geometry connected to recent experiments, we discover a nonmonotonic survival window where entanglement peaks at intermediate pump powers, defining an optimal operating point where the logarithmic negativity is strictly positive relative to the PPT null value. The surviving quantum correlations concentrate in a narrow shell near the ergosurface (defined by 
), providing a spatial fingerprint and a quantitative benchmark for quantum correlation measurements in rotating polariton flows.
