We have built a new apparatus in order to manipulate single 87Rb atoms for quantum computing. Single atoms will be loaded from a cold vapor into a microscopic dipole trap. Tests of the cooling system are under progress and first fluorescence signals have been observed in the magneto-optical trap. A high numerical aperture objective has been designed to perform tight focusing of the trapping light as well as high efficiency collection of the single atom fluorescence.
