![]() Similarly, there is no reason to expect manifestly quantum effects in biology unless they provide some competitive advantage. There is no reason to believe that all biology must exist in the correspondence limit where the underlying quantum effects can be captured by classical models. Biology does not select based on whether a mechanism can be modeled classically or quantum mechanically - only if it works. Traits will persist whenever they convey improved fitness. Keywords: Quantum Biology, Ultrafast Spectroscopy, PhotosynthesisĮvolution is the ultimate opportunist. This communication provides an overview of experimental and theoretical notions for those interested in exploiting design principles of photosynthetic energy transfer in synthetic systems. The protein bath enables the unusual observed dynamics and illustrates some simple design principles that provide direction to synthetic efforts to mimic the effect. This protection of quantum coherence can arise from multiple mechanisms, but the net effect is the same: the energetic landscape is course-grained thereby improving efficiency by effectively smoothing the rugged energetic landscape while simultaneously eliminating trap states. Experimental evidence from third-order nonlinear spectroscopies provides clear evidence of quantum coherence among excited states persisting for picoseconds despite rapid (<100fs) dephasing of quantum coherence between ground and excited states. Quantum coherence improves the quantum efficiency of excitonic energy transport within the Fenna-Matthews-Olson photosynthetic complex from the green sulphur bacterium, Chlorobium tepidum.
