The　controlled　phase　gate　is　one　of　the　most　important　logic　gates　in　the　quantum　computation　field.　In　this　paper,　we　proposed　a　protocol　for　implementing　the　two-qubit　controlled　phase　gates　with　the　help　of　cross-Kerr　nonlinearity,　optical　elements　and　the　conventional　photon　detectors,　which　are　feasible　with　existing　experimental　technology.　The　protocol　also　can　be　applied　to　implement　the　controlled　phase　gates　of　many　different　atomic　and　photonic　degrees　of　freedom　with　successful　probability　of　100%,　that　is,　our　protocol　is　efficient　and　flexible.
