Based　on　the　quantum　Zeno　dynamics,　we　propose　a　two-qubit　non-geometric　conditional　phase　gate　between　two　nitrogen-vacancy　centers　coupled　to　a　whispering-gallery　mode　cavity.　The　varying　phases　design　of　periodic　laser　can　be　used　for　realizing　non-geometric　conditional　phase　gate,　and　the　cavity　mode　is　virtually　excited　during　the　gate　operation.　Thus,　the　fidelity　of　the　gate　operation　is　insensitive　to　cavity　decay　and　the　fluctuation　of　the　preset　laser　intensity.　The　numerical　simulation　with　a　realistic　set　of　experimental　parameters　shows　that　the　gate　fidelity　0.987　can　be　within　reached　in　the　near　future.　©　2013　Chinese　Physical　Society　and　IOP　Publishing　Ltd.
