A method to reduce the entropy of a finite system of atoms to arbitrarily small values was discussed. In this method, the locations of vacancies of laser-cooled atoms in a deep optical lattice were measured. A combination of site-specific atomic state flips and state-sensitive lattice site transitions was used to calculate the distribution efficiency. The results show that the central region of the lattice has exactly one atom per site in its vibrational ground state.
