    "abstract": "We propose a scheme that allows to coherently extract cold atoms from a\nreservoir in a deterministic way. The transfer is achieved by means of\nradiation pulses coupling two atomic states which are object to different\ntrapping conditions. A particular realization is proposed, where one state has\nzero magnetic moment and is confined by a dipole trap, whereas the other state\nwith non-vanishing magnetic moment is confined by a steep microtrap potential.\nWe show that in this setup a predetermined number of atoms can be transferred\nfrom a reservoir, a Bose-Einstein condensate, into the collective quantum state\nof the steep trap with high efficiency in the parameter regime of present\nexperiments.",
