  Selective energy transport throughout a quantum network connected to more
than one reaction center can play an important role in many natural and
technological considerations in photo-systems. In this work, we propose a
method in which an excitation can be transported from the original site of the
network to one of the reaction centers arbitrarily using independent sources of
dephasing noises. We demonstrate a situation that in the absence of dephasing
noises the coherent evolution of the system has no role in the energy transport
in the network. Therefore, incoherent evolution via application of dephasing
noises throughout a selected path of the network leads to transfer the
excitation completely to a desired reaction center.
