Single photon sources (SPSs) are a key element for quantum information processing (QIP). Among other systems, single molecules are one of the promising candidates due to their high brightness and the possibility to generate single photons on demand [1]. Another crucial point for realization QIP is a quantum memory and atoms constitute a good media for its realization [2]. Here we present recent results in combining single molecule spectroscopy with the spectroscopy on the atomic vapor. A high-brightness molecule based SPS at the Sodium D-line is shown as well as slowed down photons in a Na-vapor cell. In addition, atomic vapor, serving as a very narrow notch filter, allows for an increased detection efficiency in comparison with commercial interference filters.
