    "abstract": "A quantum repeater at telecommunications wavelengths with long-lived atomic\nmemory is proposed, and its critical elements are experimentally demonstrated\nusing a cold atomic ensemble. Via atomic cascade emission, an entangled pair of\n1530 nm and 780 nm photons is generated. The former is ideal for long-distance\nquantum communication, and the latter is naturally suited for mapping to a\nlong-lived atomic memory. Together with our previous demonstration of\nphotonic-to-atomic qubit conversion, both of the essential elements for the\nproposed telecommunications quantum repeater have now been realized.",
