Abstract

By making use of the fact that photons are created in pairs in the process of parametric downconversion and by detecting them in coincidence, we propose a scheme for communication by light that should make it possible to achieve high discrimination against background. Weak light beams that are greatly overshadowed by background light should therefore be usable for an optical channel.
