中文摘要：

基于量 Zeno 动力学，我们建议在二个氮空缺中心之间的非几何的有条件的阶段门联合了到一个耳语画廊模式洞的 two-qubit。周期的激光的变化阶段设计能被用于认识到非几何的有条件的阶段门，并且洞模式在门操作期间是几乎激动的。因此，门操作的忠实对洞腐烂和预设激光紧张的变化感觉迟钝。有试验性的参数的一个现实主义的集合的数字模拟证明 0.987 能在以内的门忠实在不久的将来到达了。

英文摘要：

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.
