Project A02 aims to generate quantum-mechanical correlations between spatially separated ultracold atomic ensembles. Our strategy to achieve this is to create the non-classical correlations between atoms in different spin states and transfer them to motional states. Such entangled motional states enable a proof-of-principle operation of a gravimeter with a sensitivity beyond the Standard Quantum Limit. Ultimately, we aim to generate macroscopic, entangled states with metre-scale delocalisations together with project B07, and utilise their extreme sensitivity to probe the gravitational interaction. The project contributes to DQ-mat’s goal of enhancing quantum sensors & metrology for tests of fundamental physics.

A02 项目的目标是在空间分离的超冷原子系综之间产生量子力学相关性，我们实现这一目标的策略是在不同自旋态的原子之间创建非经典相关性，并将它们转移到运动态。最终，我们的目标是与 B07 项目一起产生具有米级离域的宏观纠缠态。利用其极高的灵敏度来探测引力相互作用，该项目有助于实现 DQ-mat 增强量子传感器和计量学以进行基础物理测试的目标。
