A bstract Recent work has shown how to understand the Page curve of an evaporating black hole from replica wormholes. However, more detailed information about structure its quantum state is needed fully dynamics evaporation. Here we study entanglement negativity, important measure in mixed states, a couple toy models holes. We find four phases dominated by different types geometries: disconnect...

We propose entanglement negativity as a fine-grained probe of measurement-induced criticality. motivate this proposal in stabilizer states, where for two disjoint subregions, comparing their "mutual negativity" and mutual information leads to precise distinction between bipartite multipartite entanglement. In measurement-only circuit that maps exactly two-dimensional critical percolation, we sh...
