This　paper　proposes　a　scheme　for　transferring　an　N-atom　state　between　two　distant　cavities　via　an　optical　fiber.　The　scheme　is　based　on　adiabatic　passage　along　a　dark　state.　In　the　scheme,　all　the　atoms　are　always　in　ground　state,　the　field　mode　of　the　fiber　remains　in　vacuum　state,　and　the　field　mode　of　the　cavities　being　excited　can　be　negligible　under　certain　conditions.　Therefore,　the　scheme　is　very　robust　against　decoherence.　The　successful　probability　of　implementing　the　quantum　state　transfer　increases　with　increasing　number　of　atoms.　Furthermore,　the　interaction　time　does　not　need　to　be　accurately　adjusted　as　long　as　the　adiabaticity　condition　is　fulfilled.　©　2009　Chin.　Phys.　Soc.　and　IOP　Publishing　Ltd.
