Abstract

We use the framework of generalized entanglement wedges to revisit the connected wedge theorem (CWT). First, we establish new upper and lower bounds on the mutual information of boundary decision regions in terms of the entropies of certain bulk scattering regions. Then, we recast the CWT into a form that extends to asymptotically flat spacetimes. We will close with some comments on related work on a CWT with converse.
