Single neutral atoms are interesting candidates for serving as qubits, the elementary objects of quantum information processing. We give an overview of experimental methods which allow us to prepare, detect, and manipulate individual neutral atoms with excellent efficiency in an optical dipole trap. We have measured long coherence times for atomic quantum state superpositions and identified the relevant decoherence mechanisms. As an application we have constructed a neutral atom quantum register from a string of atoms which can be selectively prepared in arbitrary quantum states.
