Entanglement in momentum space (A02)

A02项目的目标是在空间上分离的超冷原子系综之间产生量子力学关联。我们的策略是创建处于不同自旋态的原子之间的非经典关联，并将它们转移到运动态。这种纠缠的运动态使得重力仪能够以超过标准量子极限的灵敏度进行原理证明操作。最终，我们的目标是与B07计划一起产生具有米级离域的宏观纠缠态，并利用它们的极端敏感性来探测引力相互作用。该项目有助于DQ-MAT增强量子传感器的目标，即基础物理测试的计量学。

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.
