Fun with replicas: tripartitions in tensor networks and gravity
Geoff Penington, Michael Walter, Freek Witteveen
We introduce a new correlation measure for tripartite pure states that we call . The quantity is symmetric with respect to the subsystems , , , invariant under l…
Random tensor networks with nontrivial links
Newton Cheng, Cécilia Lancien, Geoff Penington +2
Random tensor networks are a powerful toy model for understanding the entanglement structure of holographic quantum gravity. However, unlike holographic quantum gravity, their enta…
Black hole microstates vs. the additivity conjectures
Patrick Hayden, Geoff Penington
We argue that one of the following statements must be true: (a) extensive violations of quantum information theory's additivity conjectures exist or (b) there exists a set of `dise…
Entanglement Wedge Reconstruction via Universal Recovery Channels
Jordan Cotler, Patrick Hayden, Geoffrey Penington +3
We apply and extend the theory of universal recovery channels from quantum information theory to address the problem of entanglement wedge reconstruction in AdS/CFT. It has recentl…
