  There are successful applications of the holographic AdS/CFT correspondence
to high energy and condensed matter physics. We apply the holographic approach
to photosynthesis that is an important example of nontrivial quantum phenomena
relevant for life which is being studied in the emerging field of quantum
biology. Light harvesting complexes of photosynthetic organisms are many-body
quantum systems, in which quantum coherence has recently been experimentally
shown to survive for relatively long time scales even at the physiological
temperature despite the decohering effects of their environments.
  We use the holographic approach to evaluate the time dependence of
entanglement entropy and quantum mutual information in the Fenna-Matthews-Olson
(FMO) protein-pigment complex in green sulfur bacteria during the transfer of
an excitation from a chlorosome antenna to a reaction center. It is
demonstrated that the time evolution of the mutual information simulating the
Lindblad master equation in some cases can be obtained by means of a dual
gravity describing black hole formation in the AdS-Vaidya spacetime. The wake
up and scrambling times for various partitions of the FMO complex are
discussed.
