We have realized a technique for building equidistant strings of individually addressable neutral atoms stored in a standing wave optical dipole trap. Initially, atoms are stored in random potential wells of a standing wave. Individual atoms are then extracted using "optical tweezers" and inserted at predetermined positions. Using this method, the distance between simultaneously trapped atoms can be controlled with a high efficiency and a precision corresponding to only several potential wells of the standing wave trap. Moreover, we have experimentally demonstrated that this technique is compatible with the insertion of an atom into the potential of the standing wave already occupied by another atom.
Such strings of individually addressable atoms could serve as a scalable, neutral-atom quantum register for storing and manipulating quantum information. The placement of two atoms into the same potential well would allow the investigation of collisional dynamics or chemical reactions on the level of individual atoms including the coherent and deterministic creation of a single trapped molecule from its constituents.
