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…
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…
