Transmission efficiency in photosynthetic process with quantum noise

Transmission efficiency in photosynthetic process with quantum noise Photosynthesis changes the energy from the sun into chemical energy, and its factory in cell consists from two complex of molecula which are antenna and reaction center. The absorption cross section is small. Thus, the emaining chlorophylls in the photosystem and antenna pigment protein complexes associated with the photosystems all cooperatively absorb and funnel light energy. The transfer of the excitation energy by antenna complex towards the reaction center occurs with a near unity quantum yield. We study the efficiency of the excitation energy transfer by antenna complex in photosynthesis by using the master equation for the density matrix. In this talk we show the conditions to increase the efficiency of energy transfer supposing dephasing and dissipative noise.
