    "abstract": "We report significant improvements in the retrieval efficiency of a single\nexcitation stored in an atomic ensemble and in the subsequent generation of\nstrongly correlated pairs of photons. A 50% probability to transform the stored\nexcitation into one photon in a well-defined spatio-temporal mode at the output\nof the ensemble is demonstrated. These improvements are illustrated by the\ngeneration of high-quality heralded single photons with a suppression of the\ntwo-photon component below 1% of the value for a coherent state. A broad\ncharacterization of our system is performed for different parameters in order\nto provide input for the future design of realistic quantum networks.",
