Dissipation and fluctuations are known to be sources of order in complex non-linear systems formed by many agents, as they lead to the generation of self-organized spatial or temporal structures. However, dissipation is considered to produce loss of coherence in open quantum systems, contributing to the inherent fragility of quantum states. Here, I will discuss how coherent behavior emerges in large quantum systems consisting of many atoms if dissipation is collective, in the form of correlated photon emission and absorption. Just as fireflies, ensembles of atoms that share an electromagnetic environment are able to synchronize and produce robust, macroscopic behaviors. I will discuss applications in quantum non-linear optics, and quantum information storage and processing.
