A working free-space quantum key distribution (QKD) system has been developed and tested over a 205-m indoor optical path at Los Alamos National Laboratory under fluorescent lighting conditions. Results show that free-space QKD can provide a secure real-time key distribution between parties who have a need to communicate secretly. {copyright} {ital 1998} {ital The American Physical Society}
