A　scheme　for　preparing　correlated　four-mode　states　with　controllable　weighting　factors　is　presented.　In　the　scheme,　a　sequence　of　suitably　prepared　four-level　atoms　are　orderly　sent　through　two　bimodal　cavities,　the　detection　of　all　atoms　in　ground　state　collapses　cavity　fields　to　the　desire　state.　The　distinct　advantage　of　our　scheme　is　that　the　interaction　time　can　be　greatly　shortened,　which　is　important　in　view　of　decoherence.　(c)　2007　Elsevier　B.V.　All　rights　reserved.
