Four-mode quantum sensing and Fisher information in a spin-orbit-coupled Bose gas
Fei Zhu, Zheng Tang, Liang Zeng +2
Multi-mode squeezing and entanglement are important resources in quantum metrology and sensing. For spin-1/2 Bose-Einstein condensates subject to spin-orbit coupling (SOC), previou…
Dynamical generation of geometric squeezing in interacting Bose-Einstein condensates
Li Chen, Fei Zhu, Zheng Tang +3
When the rotating frequency of a non-interacting Bose-Einstein condensate (BEC) confined in a weak anisotropic harmonic potential is suddenly quenched to its trapping frequency, th…
Rapid passage to ordered states in Rydberg atom arrays
Liang Zeng, Fei Zhu, Li Chen +1
Given a finite lifetime, a ubiquitous challenge in quantum systems is how to prepare a target state in the shortest possible time. This issue is particularly relevant for Rydberg a…
Floquet geometric squeezing in fast-rotating condensates
Li Chen, Fei Zhu, Yunbo Zhang +1
Constructing and manipulating quantum states in fast-rotating Bose-Einstein condensates (BEC) has long stood as a significant challenge as the rotating speed approaching the critic…
