Purely GHZ-like entanglement is forbidden in holography
Vijay Balasubramanian, Monica Jinwoo Kang, Charlie Cummings +2
We provide evidence that three-party entanglement signals in holography obey a relation that is not satisfied by generalized Greenberger-Horne-Zeilinger (GHZ) states. Using propose…

Diffeomorphism invariant tensor networks for 3d gravity
Vijay Balasubramanian, Charlie Cummings
Tensor networks prepare states that share many features of states in quantum gravity. However, standard constructions are not diffeomorphism invariant and do not support an algebra…

Multipartite Entanglement Structure of Fibered Link States
Vijay Balasubramanian, Charlie Cummings
We study the patterns of multipartite entanglement in Chern-Simons theory with compact simple gauge group and level for states defined by the path integral on ``link comple…
