Abstract

The controlled generation of single photons is mandatory for new applications of quantum communication, in particular for truly secure quantum cryptography [1]. Various solutions based on the fluorescence of single atom, ions or organic molecules have been demonstrated already [2]. However, they are either rather difficult to perform, need expensive equipment or can generate only a very limited number of emissions. Here, we present an all-solid-state solution promising low costs and unprecedented stability.
