Abstract :
This study demonstrates the existence of noise assisted transport in the Fenna-Matthew-Olson (FMO) complex, a light-harvesting complex found in photosynthetic green sulphur bacteria. Result shows how local dephasing enhances the transport process in the FMO complex. In addition, the robustness of the mechanism under local disorder reveals that energy transport in nature is not sensitive to the finer details of the photosynthetic system. A preliminary evidence is also presented, which suggests that the existence of quantum entanglement in the FMO complex can be probed using 2D femtosecond spectroscopic technique.
