    "abstract": "In order for quantum communications systems to become widely used, it will\nprobably be necessary to develop quantum repeaters that can extend the range of\nquantum key distribution systems and correct for errors in the transmission of\nquantum information. Quantum logic gates based on linear optical techniques\nappear to be a promising approach for the development of quantum repeaters, and\nthey may have applications in quantum computing as well. Here we describe the\nbasic principles of logic gates based on linear optics, along with the results\nfrom several experimental demonstrations of devices of this kind. A prototype\nsource of single photons and a quantum memory device for photons are also\ndiscussed. These devices can be combined with a four-qubit encoding to\nimplement a quantum repeater.",
