A Brownian particle's random motions can be rectified by a periodic potentialenergy landscape that alternates between two states, even if both states arespatially symmetric. If the two states differ only by a discrete translation,the direction of the ratchet-driven current can be reversed by changing theirrelative durations. We experimentally demonstrate flux reversal in a symmetrictwo-state ratchet by tracking the motions of colloidal spheres moving throughlarge arrays of discrete potential energy wells created with dynamicholographic optical tweezers. The model's simplicity and high degree ofsymmetry suggest possible applications in molecular-scale motors.Comment: 4 pages, 5 figures, accepted for publication in Physical Review E,  Rapid Communication
