论文摘要
原子钟的准确性部分取决于相关原子过渡的带宽。在这里，我们考虑了$ n $原子的合奏，其过渡频率受环境影响或其他因素的独立扰动。我们考虑使用量子ZENO效应锁定原子的相对相的可能性，这将使其有效带宽降低$ 1/\ sqrt {n} $。我们分析了一个示例，其中量子ZENO效应可用于锁定一对原子的相对相，然后可以确定经过的时间。实际应用可能需要$ n >> 1美元才能达到良好的信噪比。
The accuracy of an atomic clock depends in part on the bandwidth of the relevant atomic transitions. Here we consider an ensemble of $N$ atoms whose transition frequencies have been independently perturbed by environmental effects or other factors. We consider the possibility of using the quantum Zeno effect to lock the relative phase of the atoms, which would decrease their effective bandwidth by a factor of $1/\sqrt{N}$. We analyze an example in which the quantum Zeno effect can be used to lock the relative phase of a pair of atoms, after which the elapsed time can be determined. Practical applications may require $N>>1$ in order to achieve a good signal-to-noise ratio.
