Abstract: We study this question using the AdS/CFT correspondence, where computation in the presence of gravity can be related to non-gravitational physics in the boundary theory. In AdS/CFT, computations which happen locally in the bulk are implemented in a particular non-local form in the boundary, which in general requires distributed entanglement. This is made most precise in the context of certain black hole solutions. There, the black hole area is equal to the mutual information available in the boundary to perform the computation non-locally. We argue the complexity of the local operation controls the amount of entanglement needed to implement it non-locally, and that this consequently places constraints on computation in the presence of gravity.

Lunch will be provided, following the talk, on the lawn north of the Bridge Arcade
