    "abstract": "A working free-space quantum key distribution (QKD) system has been developed\nand tested over an outdoor optical path of ~1 km at Los Alamos National\nLaboratory under nighttime conditions. Results show that QKD can provide secure\nreal-time key distribution between parties who have a need to communicate\nsecretly. Finally, we examine the feasibility of surface to satellite QKD.",
