    "abstract": "We create independent, synchronized single-photon sources with built-in\nquantum memory based on two remote cold atomic ensembles. The synchronized\nsingle photons are used to demonstrate efficient generation of entanglement.\nThe resulting entangled photon pairs violate a Bell\u0027s Inequality by 5 standard\ndeviations. Our synchronized single photons with their long coherence time of\n25 ns and the efficient creation of entanglement serve as an ideal building\nblock for scalable linear optical quantum information processing.",
