摘要:

产生并利用纠缠的能力对量子传感与量子模拟领域至关重要,而超冷原子-腔系统为这项工作提供了理想的平台。本文提出了一种无需电子相互作用、仅在腔内原子的运动态之间产生并调控纠缠的方法。我们证明这种相互作用源自通用的原子-腔模型,并讨论了腔频移响应原子运动的作用。这种腔响应会在原子动量态之间引发多种不同的压缩相互作用。此外,我们还证明当原子形成密度光栅时,集体运动会产生单轴扭曲、多体能隙,且即使存在噪声也能产生具备计量学应用价值的纠缠。值得注意的是,近期有实验证实该机制会在共腔模中的原子之间产生有效的动量交换相互作用。该系统提供了一种高度可调的多体量子传感器与模拟器。

英文摘要:

The ability to create and harness entanglement is crucial to the fields of quantum sensing and simulation, and ultracold atom-cavity systems offer pristine platforms for this undertaking. Here, we present a method for creating and controlling entanglement between solely the motional states of atoms in a cavity without the need for electronic interactions. We show this interaction arises from a general atom-cavity model, and discuss the role of the cavity frequency shift in response to atomic motion. This cavity response leads to many different squeezing interactions between the atomic momentum states. Furthermore, we show that when the atoms form a density grating, the collective motion leads to one-axis twisting, a many-body energy gap, and metrologically useful entanglement even in the presence of noise. Noteably, an experiment has recently demonstrated this regime leads to an effective momentum-exchange interaction between atoms in a common cavity mode. This system offers a highly tunable, many-body quantum sensor and simulator.
