利用原子光脉冲对原子进行相干操纵是原子干涉测量的核心。实现高脉冲效率对于增强条纹对比度和灵敏度是至关重要的，特别是对于使用增加数量的脉冲的大动量传递干涉仪。我们进行了一项调查，优化脉冲的频域，通过使用定制的多色光场，并证明了可能性，提供高效率和弹性的原子光脉冲，即使在不均匀的原子云和激光束的情况下。我们发现，这种方法是能够在很长的询问时间，尽管自发辐射，并实现实验相关的云的脉冲效率。这克服了大动量转移的一些最严格的障碍，并有可能降低原子干涉仪的复杂性。我们发现，多色光脉冲可以增强基于单光子的大动量转移原子干涉测量的动量分裂与实验可访问的参数，这是一个显着的改进，在国家的最先进的方法的好处超出原子干涉测量，并可能使突破性的进展量子态操纵。
Coherent manipulation of atoms with atom-optic light pulses is central to atom interferometry. Achieving high pulse efficiency is essential for enhancing fringe contrast and sensitivity, in particular for large-momentum transfer interferometers which use an increased number of pulses. We perform an investigation of optimizing the frequency domain of pulses by using tailored polychromatic light fields, and demonstrate the possibility to deliver high-efficiency and resilient atom-optic pulses even in the situation of inhomogeneous atomic clouds and laser beams. We find that this approach is able to operate over long interrogation times despite spontaneous emission and to achieve experimentally relevant pulse efficiencies for clouds up to. This overcomes some of the most stringent barriers for large-momentum transfer and has the potential to reduce the complexity of atom interferometers. We show that polychromatic light pulses could enhance single-photon-based large-momentum transfer atom interferometry—achievingof momentum splitting with experimentally accessible parameters, which represents a significant improvement over the state-of-the art. The benefits of the method extend beyond atom interferometry and could enable groundbreaking advances in quantum state manipulation.
