Quantum enhanced sensing by echoing spin-nematic squeezing in atomic Bose-Einstein condensate
Tian-Wei Mao, Qi Liu, Xin-Wei Li +6
Quantum entanglement can provide enhanced precision beyond standard quantum limit (SQL), the highest precision achievable with classical means. It remains challenging, however, to…
Critically-enhanced spin-nematic squeezing and entanglement in dipolar spinor condensates
Qing-Shou Tan, Yixiao Huang, Qiong-Tao Xie +1
We study the quantum critical effect enhanced spin-nematic squeezing and quantum Fisher information (QFI) in the spin-1 dipolar atomic Bose-Einstein condensate. We show that the qu…
Optimal Conventional Measurements for Quantum-Enhanced Interferometry
Wei Zhong, Yixiao Huang, Xiaoguang Wang +1
A major obstacle to attain the fundamental precision limit of the phase estimation in an interferometry is the identification and implementation of the optimal measurement. Here we…
Dephasing-assisted parameter estimation in the presence of dynamical decoupling
Qing-Shou Tan, Yixiao Huang, Le-Man Kuang +1
We study the dephasing-assisted precision of parameter estimation (PPE) enhancement in atom interferometer under dynamical decoupling (DD) pulses. Through calculating spin squeezin…
Macroscopic quantum coherence in spinor condensates confined in an anisotropic potential
Yixiao Huang, Yunbo Zhang, Rong Lü +2
We investigate the macroscopic quantum coherence of a spin-1 Rb condensate confined in an anisotropic potential. Under the single-mode approximation, we show that the system can be…
Fisher information manifestation of dynamical stability and transition to self-trapping for Bose-Einstein condensates
Yixiao Huang, Wei Zhong, Zhe Sun +1
We investigate dynamical stability and self-trapping for Bose-Einstein condensates in a symmetric double well. The relation between the quantum Fisher information and the stability…
