Abstract: Photosynthetic light harvesting of plants and bacteria in vivo is characterized by the remarkable capability of producing electron-hole pairs from absorbed photons with near unit quantum efficiency under weak illumination conditions. While much experimental and theoretical work has been devoted to analysis of the excited state energy transfer following the initial process of photoexcitation, less attention has focused on the absorption event itself. In this talk I shall describe a new generation of experimental and theoretical studies using quantum light sources that address this using the interaction of heralded individual incident photons with photosynthetic complexes, and discuss the new microscopic information that these studies can reveal.
