    "abstract": "We present a full implementation of a quantum key distribution (QKD) system\nwith a single photon source, operating at night in open air. The single photon\nsource at the heart of the functional and reliable setup relies on the pulsed\nexcitation of a single nitrogen-vacancy color center in diamond nanocrystal. We\ntested the effect of attenuation on the polarized encoded photons for inferring\nlonger distance performance of our system. For strong attenuation, the use of\npure single photon states gives measurable advantage over systems relying on\nweak attenuated laser pulses. The results are in good agreement with\ntheoretical models developed to assess QKD security.",
