Abstract

Heralding a single photon from a photon pair generated by spontaneous parametric down-conversion is the most reliable way to generate pure, single mode photons up to date [1]. Next step is to tailor photon properties, such as temporal and spatial profiles and polarization pattern. The motivation is the following - tailored photons are superior in a number of optical tasks, where light intensity is restricted to a single quanta level. Amongst them we recall efficient excitation of a single quantum emitter (single atom, molecule, quantum dot, etc.), quantum information processing with single photons and quantum emitters.
