In the article they analyse the recent work on coherence in photosynthetic complexes, in particular, the results from femtosecond multidimensional spectroscopy studies on the Fenna-Matthews-Olson (FMO) protein, a light-harvesting complex from green sulfur bacteria, which has taken on an exemplary role in quantum biology.
Their results unambiguously show the absence of long-lived interexciton coherence on the time scales relevant for the energy transfer in this system, both at cryogenic and physiological temperatures. Thus it is recovered that nature instead of preserving coherence and avoiding dissipation, embraces the latter to facilitate the efficient and robust energy collection.
