论文摘要
旋转挤压方案允许动态生成大规模相关的量子多体状态，该状态可用于纠缠增强的计量和技术。我们研究了一种量子模拟器，该量子模拟器生成扭曲动力学，该动力学在具有偶极相互作用的两个组分玻色式模型中实现。我们表明，超氟相之间的接触和远程偶极相互作用的相互作用激活了各向异性的两轴反击机制，从而加速了自旋挤压动力学并允许在光谱测量中获得Heisenberg限制的精度。
The spin squeezing protocols allow the dynamical generation of massively correlated quantum many-body states, which can be utilized in entanglement-enhanced metrology and technologies. We study a quantum simulator generating twisting dynamics realized in a two-component Bose-Hubbard model with dipolar interactions. We show that the interplay of contact and long-range dipolar interactions between atoms in the superfluid phase activates the anisotropic two-axis counter-twisting mechanism, accelerating the spin squeezing dynamics and allowing the Heisenberg-limited accuracy in spectroscopic measurements.
