Abstract
We introduce a fully coherent way for directed state transport of an atom in 1D optical lattices. In this method the state of an atom (quantum information) transfer by regularly performing phase shifts on the lattice potential during the free evolution of the system. This method use for realizing quantum gates and entanglement generation by bringing two qubits in the proximity of each other and let them interact. Our scheme is robust against possible imperfections in the experimental setups and is fully accessible to the current experiments.
