In this paper, we have looked at the system of two cavities, each of them having N atoms, and both connected by an optical fiber. The process for the construction of a SWAP gate among two spatially separated cavities and N atoms via a stimulated Raman adiabatic passage has been presented. It does not require a composition of elementary gates from a universal set and it shows that a highly reliable SWAP gate is achievable based on adiabatic passage. The SWAP operation involves three types of atomic states: with 0 excitation, single excitation and two excitations. The two-excitation state corresponds to double excitation of the atoms. Possible pathways for information transfer for this double excitation the explained. In this scheme the last state involves 1 atom in the excited state and N - 1 atoms in the ground state of cavity one and one atom in the excited state and N - 1 atoms in the ground state of cavity 2 and this is not connected to the rest of the 7 states.
