论文摘要
通过数值和分析，在原子干涉法的背景下，通过数值和分析对双峰和Spin-1 Bose-Einstein冷凝物进行数值和分析分析，对通过量子Fisher信息进行动力稳定的方案。该方案由扭曲动力学组成，然后是一个状态的单个旋转，该旋转限制了平均场相空间中稳定中心固定点的进一步演变。所产生的纠缠水平是秩序或大于旋转时刻的阶段。证明，均等的读数测量量量化了整个进化过程中的纠缠水平。
A scheme for dynamical stabilization of entanglement quantified by the quantum Fisher information is analyzed numerically and analytically for bimodal and spin-1 Bose-Einstein condensates in the context of atomic interferometry. The scheme consists of twisting dynamics followed by a single rotation of a state which limits further evolution around stable center fixed points in the mean-field phase space. The resulting level of entanglement is of the order or larger than at the moment of rotation. It is demonstrated that the readout measurement of parity quantifies the level of entanglement during entire evolution.
