Abstract :
An existing free space quantum key distribution system based on entangled photons is adapted for daylight operation. Filtering in spectral, spatial and temporal domain is optimized to maximize the signal to noise ratio so as to cope with sunlight conditions. Hardware and software are adapted for increased data processing requirements.
