Abstract

A scheme of a single photon source for quantum informatics applications based on the spontaneous parametric scattering effect is proposed and a quantum cryptography setup using it is presented. The system is compared to the alternative ones that operate with attenuated classic light.

Keywords: quantum cryptography, spontaneous parametric scattering, biphotons, sidebands.
