To utilize a single atom as a quantum bit for a quantum computer requires exquisite control over the internal and external degrees of freedom. This thesis develops techniques for controlling the external degrees of freedom of individual atoms. In the first part of this thesis, individual atoms are trapped and detected non-destructively by the addition of cooling beams in an optical lattice. This non-destructive imaging technique led to atomic storage times of two minutes in an optical lattice. The second part of thesis incorporated the individual atoms into a high finesse cavity. Inside this optical cavity, atoms are cooled and non-destructively observed for up to 10 seconds.
