Dephasing-assisted selective incoherent quantum transport

Quantum Physics 2015-10-28 v2

Abstract

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.
