ULTRA-FAST AND SUPER-EFFICIENT. "One of the simplest and most well-studied examples is the light-harvesting apparatus of green-sulphur bacteria. What is remarkable is the observed efficiency of this and other photosynthetic units. Almost every photon (nearly 100%) that is absorbed is successfully transferred to the reaction centre, even though the intermediate electronic excitations are very short-lived (~ 1 ns)." https://lnkd.in/eRUdQZj View in LinkedIn

ANTENNA PROTEINS. "Photosynthesis makes use of sunlight to convert carbon dioxide into useful biomass and is vital for life on Earth. Crucial components for the photosynthetic process are antenna proteins, which absorb light and transmit the resultant excitation energy between molecules to a reaction centre." https://lnkd.in/edvYfjM View in LinkedIn

QUANTUM COHERENCE. "Direct evidence for the presence of quantum coherence over appreciable length scales and timescales in the FMO complex was observed by Engel et al. Since that time a huge body of literature has arisen, and further experiments suggest that the coherence is non-negligible even at room temperature, for up to 300 fs." https://lnkd.in/eRUdQZj View in LinkedIn

"THE QUANTUM COHERENCE manifests itself in characteristic, directly observable quantum beating signals among the excitons within the Chlorobium tepidum FMO complex at 77 K. This wavelike characteristic of the energy transfer within the photosynthetic complex can explain its extreme efficiency, in that it allows the complexes to sample vast areas of phase space to find the most efficient path." https://lnkd.in/e7zeiN5 View in LinkedIn

PHOTONS STRIKING PLANTS. "Coherent quantum waves can exist in two or more states at the same time, so coherent excitons would be able to move through the forest of antenna molecules by two or more routes at once. In fact, they could simultaneously explore a multitude of possible options, and automatically select the most efficient path to the reaction centre." https://lnkd.in/eDJed9B View in LinkedIn
