    "abstract": "We describe a simple experimental technique which allows to store a single\nRubidium 87 atom in an optical dipole trap. Due to light-induced two-body\ncollisions during the loading stage of the trap the maximum number of captured\natoms is locked to one. This collisional blockade effect is confirmed by the\nobservation of photon anti-bunching in the detected fluorescence light. The\nspectral properties of single photons emitted by the atom were studied with a\nnarrow-band scanning cavity. We find that the atomic fluorescence spectrum is\ndominated by the spectral width of the exciting laser light field. In addition\nwe observe a spectral broadening of the atomic fluorescence light due to the\nDoppler effect. This allows us to determine the mean kinetic energy of the\ntrapped atom corresponding to a temperature of 105 micro Kelvin. This simple\nsingle-atom trap is the key element for the generation of atom-photon\nentanglement required for future applications in quantum communication and a\nfirst loophole-free test of Bell\u0027s inequality.",
