    "abstract": "We report experimental generation of non-classically correlated photon pairs\nfrom collective emission in a room-temperature atomic vapor cell. The\nnonclassical feature of the emission is demonstrated by observing a violation\nof the Cauchy-Schwarz inequality. Each pair of correlated photons are separated\nby a controllable time delay up to 2 microseconds. This experiment demonstrates\nan important step towards the realization of the Duan-Lukin-Cirac-Zoller scheme\nfor scalable long-distance quantum communication.",
