Entanglement Wedge Cross Section Inequalities from Replicated Geometries
arXiv:2106.02640 · doi:10.1007/JHEP07(2021)113
Abstract
We generalize the constructions for the multipartite reflected entropy in order to construct spacetimes capable of representing multipartite entanglement wedge cross sections of differing party number as Ryu-Takayanagi surfaces on a single replicated geometry. We devise a general algorithm for such constructions for arbitrary party number and demonstrate how such methods can be used to derive novel inequalities constraining mulipartite entanglement wedge cross sections.
