Abstract
We develop a quantum scattering model to describe the exciton transport through the
Fenna-Matthews-Olson(FMO) complex. It is found that the exciton transport involved
the optimal quantum coherence is more efficient than that involved classical behavior
alone. Furthermore, we also find that the quantum resonance condition is easier to
be fulfilled in multiple pathways than that in one pathway. We then definitely demonstrate
that the optimal distribution of the pigments, the multitude of energy delivery pathways
and the quantum effects, are combined together to contribute to the perfect energy
transport in the FMO complex.
