【 摘 要 】

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