论文摘要
光脉冲原子干涉仪中光学元件的类似物是由物质波与光场的相互作用产生的。因此，这些磁场具有量子特性，从根本上导致观察到的干扰的可见性降低。这种损失是有关原子路径的编码信息的结果。但是，原子光学元素的量子性质还为减少这种影响提供了额外的自由度：我们证明，所有光场之间的纠缠可用于消除有关原子路径的信息，并通过部分恢复可见度。因此，我们的工作突出了互补性在原子间质量测定实验中的作用。
The analogs of optical elements in light-pulse atom interferometers are generated from the interaction of matter waves with light fields. As such, these fields possess quantum properties, which fundamentally lead to a reduced visibility in the observed interference. This loss is a consequence of the encoded information about the atom's path. However, the quantum nature of the atom-optical elements also gives an additional degree of freedom to reduce such effects: We demonstrate that entanglement between all light fields can be used to erase information about the atom's path and by that to partially recover the visibility. Thus, our work highlights the role of complementarity on atom-interferometric experiments.
