Single-photon-triggered spin squeezing with decoherence reduction in optomechanics via phase matching
Zhucheng Zhang, Lei Shao, Wangjun Lu +4
Quantum spin squeezing is an important resource for quantum information processing, but its squeezing degree is not easy to preserve in an open system with decoherence. Here, we pr…
Quantum interferometry for rotation sensing in an optical microresonator
Weijun Cheng, Zhihai Wang, Xiaoguang Wang
We theoretically propose a scheme to perform rotation sensing in a Whispering-gallery-mode resonator setup. With the assistance of a large detuned two-level atom, which induces the…
Rotating wave approximation for quadrupole interaction with high spin
Wenkui Ding, Xiaoguang Wang
Rotating wave approximation in a quantum spin system driven by a linearly polarized alternating magnetic field with quadrupole interaction presents is investigated in detail in thi…
Parametrized protocol achieving the Heisenberg limit in the optical domain via dispersive atom-light interactions
Yuguo Su, Xiaoguang Wang
The strong and collective atom-light interactions in cavity-QED systems perform manifold benefits in quantum-enhanced measurements. Here, we study the time-reversal protocol that h…
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…
Incorporating Heisenberg's Uncertainty Principle into Quantum Multiparameter Estimation
Xiao-Ming Lu, Xiaoguang Wang
The quantum multiparameter estimation is very different from the classical multiparameter estimation due to Heisenberg's uncertainty principle in quantum mechanics. When the optima…
