  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. With the environment acting 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
adjust the efficiency of the quantum transport scheme by varying the spacing
between energy levels of the system, by decreasing the ground state energy
level of the environment, and by weakening the coupling between the system and
the environment. A possible realization of this quantum transport scheme using
ultracold atoms in a lattice coupled to a reservoir of energy excitations is
briefly discussed at the end of this paper.
