A　scheme　is　proposed　for　the　generation　of　two-atom　maximally　entangled　states　and　realization　of　quantum　logic　gates　and　teleportation　with　cavity　QED,　The　scheme　does　nor　require　the　transfer　of　quantum　information　between　the　atoms　and　cavity.　In　the　scheme　the　cavity　is　only　virtually　excited　and　thus　the　requirement　on　the　quality　factor　of　the　cavities　is　greatly　loosened.
