Abstract
In the recent years the study of biological systems in which quantum dynamics is visible has been attended recently. Theory of open quantum system is used to describe the dynamics of such systems commonly. By understanding these processes are performed, their mechanism can be used to build new nanostructures for quantum transfer and as well as to build optimal solar cells. One of these biological systems is photosynthesis that is main source of energy for plants algae and some kinds of bacteria. We will consider quantum dynamics of photosynthetic Fenna-Matthew-Olson (FMO) complex. For this purpose, we using the variational quantum algorithm consisting of quantum and classical computers. Parametric quantum state preparations and quantum measurements are performed on the quantum computer and parameters optimized on the classic computer. We obtain trace distance and fidelity between exact and hybrid states. The output of the algorithm is compatible with the exact calculation.
