Entanglement in momentum space (A02)

A02计划旨在产生空间分离的超冷原子系综之间的量子力学相关性。我们实现这一目标的策略是在不同自旋态的原子之间建立非经典相关性，并将它们转移到运动态。这种纠缠的运动状态使重力仪的原理验证操作具有超过标准量子极限的灵敏度。最终，我们的目标是与B07项目一起产生具有米尺度离域的宏观纠缠态，并利用它们的极端灵敏度来探测引力相互作用。该项目有助于DQ-mat提高量子传感器和计量学的目标，用于基础物理测试。

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.
