摘要：

我们提出了一个方案，可以有效地恢复不动点的重复Jaynes-Cummings相互作用的量子动力学原子态测量，当相互作用时间随机波动。它是基于选择叠加的原子状态，其相位相关性往往抑制每个单独的状态的相位波动。一个建议的实现涉及到一个单一的Fock状态的腔场分布的收敛进行有条件的测量两个能级原子的波动速度后，他们穿过腔。另一个实现涉及到一个被困离子的内部运动状态耦合随机波动。通过对离子内部状态的条件测量，使其运动态收敛到Fock态。

英文摘要：

We propose a scheme which can effectively restore fixed points in the quantum dynamics of repeated Jaynes-Cummings interactions followed by atomic state measurements, when the interaction times fluctuate randomly. It is based on selection of superposed atomic states whose phase correlations tend to suppress the phase fluctuations of each separate state. One suggested realization involves the convergence of the cavity field distribution to a single Fock state by conditional measurements performed on two-level atoms with fluctuating velocities after they cross the cavity. Another realization involves a trapped ion whose internal-motional state coupling fluctuates randomly. Its motional state is made to converge to a Fock state by conditional measurements of the internal state of the ion.
