Dissipation induced quantum transport on a finite one-dimensional lattice
Keywords:
Open quantum systems, quantum transportAbstract
We construct a dissipation induced quantum transport scheme by coupling a finite lattice of $N$ two-level systems to an environment with a discrete number of energy levels and which acts as a reservoir of energy excitations. We show that the coupling between the system and the environment gives rise to a mechanism for excited states of the system to be efficiently transported from one end of the lattice to another. We also show that we can maximize the efficiency of the quantum transport mechanism by varying the spacing between energy levels of the system, by decreasing the ground state energy level of the environment, and by decreasing the number of energy levels in the environment.
