The studies of the initial energy excitation propagation in light-harvesting proteins, in particular in the Fenna-Matthews-Olson protein complex, have recently been enriched with the discussion of quantum-coherent excitation transfer and genuine quantum effects such as entanglement. The presence of quantum-coherent energy transfer and quantum entanglement during excitation transfer have been linked to an improved energy transport efficiency in light harvesting complexes.
In this presentation, we investigate the theoretical modeling that underlies the excitation transfer dynamics in light harvesting complexes, and we elucidate its impact on genuine quantum effects such as entanglement.
