我们研究了基于量子芝诺动力学的双模腔在共振和大失谐条件下的一步实现Fredkin门，从而降低了实验操作的复杂性。通过数值计算讨论了腔衰和原子自发发射的影响。结果表明，两种模型的保真度和成功概率对空腔衰减具有鲁棒性，对大失谐模型的原子自发发射不敏感。与大失谐模型相比，共振模型的相互作用时间较短。
We study one-step implementation of the Fredkin gate in a bi-modal cavity under both resonant and large detuning conditions based on quantum Zeno dynamics, which reduces the complexity of experiment operations. The influence of cavity decay and atomic spontaneous emission is discussed by numerical calculation. The results demonstrate that the fidelity and the success probability are robust against cavity decay in both models and they are also insensitive to atomic spontaneous emission in the large detuning model. In addition, the interaction time is rather short in the resonant model compared to the large detuning model.
