  We propose a robust scheme to prepare three-dimensional entanglement states
between a single atom and a Bose-Einstein Condensate (BEC) via stimulated Raman
adiabatic passage (STIRAP) techniques. The atomic spontaneous radiation, the
cavity decay, and the fiber loss are efficiently suppressed by the engineering
adiabatic passage. Our scheme is also robust to the variation of atom number in
the BEC.
