A　scheme　is　presented　for　realizing　two-atom　quantum　logic　gates　with　a　single　resonant　interaction.　The　scheme　does　not　use　the　cavity　mode　as　the　data　bus　and　only　requires　a　single　resonant　interaction　of　the　atoms　with　a　cavity　mode.　Thus　the　scheme　is　very　simple　and　the　interaction　time　is　very　short,　which　is　important　in　view　of　decoherence.　Quantum　information　can　be　directly　transferred　from　one　atom　to　another　atom　using　this　idea.　The　scheme　can　also　be　generalized　to　the　ion　trap　system.　©　2005　The　American　Physical　Society.
