论文摘要
我们提出了一种实验可行的方法，可通过使用稀有型 - $ s $ - 波散射光晕在物质波系统中证明物质波系统中的量子非局部性，该方法是通过撞击氦Bose-Einstein冷凝物产生的。讨论了这种方法的理论基础，并通过实验量化了其适用性。作为概念的证明，我们证明了$ v = 0.42（9）$的干涉量学可见性，对应于Clauser-Horne-Horne-Holt-Holt（CHSH）版本的最大cshs-bell参数，$ s = 1.1（1）$，在原子之间的铃铛不平等，bell不平等的版本，分别为$ \ sim 4 $ sim 4 $相关长度。这构成了朝着大规模颗粒自由度的贝尔不平等侵犯违反钟的不平等程度的重要一步，并可能测量重力敏感的系统中量子效应。
We present an experimentally viable approach to demonstrating quantum non-locality in a matter wave system via a Rarity-Tapster interferometer using two $s$-wave scattering halos generated by colliding helium Bose-Einstein condensates. The theoretical basis for this method is discussed, and its suitability is experimentally quantified. As a proof of concept, we demonstrate an interferometric visibility of $V=0.42(9)$, corresponding to a maximum CSHS-Bell parameter of $S=1.1(1)$, for the Clauser-Horne-Shimony-Holt (CHSH) version of the Bell inequality, between atoms separated by $\sim 4$ correlation lengths. This constitutes a significant step towards a demonstration of a Bell inequality violation for motional degrees of freedom of massive particles and possible measurements of quantum effects in a gravitationally sensitive system.
