The qudit system may offer great flexibilities for quantum information
processing. We investigate the possibility of realizing elementary quantum gates
between two high-dimensional atoms in distant cavities coupled by an optical
fiber. We show that highly reliable special swap gate is achievable by different
detuning. The numerical simulation shows that the proposed elementary gate is
robust against the atomic spontaneous decay, photon leakage of cavities and
optical fibers by choosing the experimental parameters appropriately.
