We present a scheme for conditionally teleporting an unknown atomic state in cavity QED, which requirestwo atoms and one cavity mode. The translational degrees of freedom of the atoms are taken into account usingthe optical Stern-Gerlach model. We show that successful teleportation with probability 1/2 can be achievedthrough local measurements of the cavity photon number and atomic positions. Neither direct projection ontohighly entangled states nor holonomous interaction-time constraints are required.
