The influence of background light on satellite-to-ground free-space quantum key distribution (QKD) is investigated. By comparing the number of noise photons to that of the signal photons per pulse, the technical requirements for a practical system are evaluated. We show that satellite-to-ground QKD is feasible with currently available technology even under full moonlight.
