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.
