    "abstract": "We report the full implementation of a quantum cryptography protocol using a\nstream of single photon pulses generated by a stable and efficient source\noperating at room temperature. The single photon pulses are emitted on demand\nby a single nitrogen-vacancy (NV) color center in a diamond nanocrystal. The\nquantum bit error rate is less that 4.6% and the secure bit rate is 9500\nbits/s. The overall performances of our system reaches a domain where single\nphotons have a measurable advantage over an equivalent system based on\nattenuated light pulses.",
