In recent years, a number of examples of bulk gravitational theories have arisen whose boundary duals are not individual quantum field theories but ensembles thereof. By considering some exactly solvable examples of ensemble holography, I will address two questions: When does an ensemble of CFTs have a bulk dual? When is a topological field theory, summed over a given set of topologies, dual to an ensemble of boundary CFTs? The answers to both questions will turn out to be governed by codes.
