New theoretical work appeared in PRX and was highlighted in an APS Physics Synopsis. It marks a major advance in our understanding of the exciting and highly active topic of quantum optical systems and dynamics for use in information processing. Specifically, we show that associative memory---the storage and recall of multiple memories---is possible in a system of atoms and photons. The photonic modes serve as the synapses connecting a network of superradiant atomic spin ensembles. Memories are encoded in the atomic positions and can be accessed through the input and output of patterns of light. Ours is the first to present a practicable scheme based on already-demonstrated quantum optical technology.
