We combine matter-wave interferometry and cavity optomechanics to propose a coherent matter-light interface based on mechanical motion at the quantum level. We demonstrate a mechanism that is able to transfer non-classical features imprinted on the state of a matter-wave system to an optomechanical device, transducing them into distinctive interference fringes. This provides a reliable tool for the inference of quantum coherence in the particle beam. Moreover, we discuss how our system allows for intriguing perspectives, paving the way to the construction of a device for the encoding of quantum information in matter-wave systems. Our proposal, which highlights previously unforeseen possibilities for the synergistic exploitation of these two experimental platforms, is explicitly based on existing technology, available and widely used in current cutting-edge experiments.
我们结合物质波干涉测量法和腔光力学，提出了一种基于量子水平机械运动的相干物质-光界面。我们展示了一种机制，该机制能够将印刻在物质波系统状态上的非经典特征转移到一个光机械装置上，并将它们转换为独特的干涉条纹。这为推断粒子束中的量子相干性提供了一个可靠的工具。此外，我们讨论了我们的系统如何带来有趣的前景，为构建用于在物质波系统中编码量子信息的装置铺平道路。我们的提议明确基于现有技术，这些技术在当前前沿实验中可用且广泛使用，它突出了这两个实验平台协同利用之前未被预见的可能性。
