    "abstract": "A few 85Rb atoms were trapped in a micron-size magneto-optical trap with a\nhigh quadrupole magnetic-field gradient and the number of atoms was precisely\ncontrolled by suppressing stochastic loading and loss events via real-time\nfeedback on the magnetic field gradient. The measured occupation probability of\nsingle atom was as high as 99%. Atoms up to five were also trapped with high\noccupation probabilities. The present technique could be used to make a\ndeterministic atom source.",
