Observing Bell Inequality Violation Beyond the Qubit Bound in a Spinor Bose--Einstein Condensate
Wenxin Xu, Junshuang Hu, Guillem Müller-Rigat +4
Correlations allowed by quantum mechanics can defy any classical explanation, with Bell nonlocality standing as their most profound and operationally powerful manifestation. While…
Optimal Control of Spin Squeezing in 2D Finite-Range Interacting Systems
Ang Li, Ling-Na Wu, Li You
Spin squeezing serves as both a fundamental witness of quantum entanglement and a critical resource for quantum-enhanced metrology. While generating substantial spin squeezing in f…
Pound-Drever-Hall Feedforward: Laser Phase Noise Suppression beyond Feedback
Yu-Xin Chao, Zhen-Xing Hua, Xin-Hui Liang +3
Pound-Drever-Hall (PDH) laser frequency stabilization is a powerful technique widely used for building narrow-linewidth lasers. This technique is however ineffective in suppressing…
Detection of entangled states supported by reinforcement learning
Jia-Hao Cao, Feng Chen, Qi Liu +4
Discrimination of entangled states is an important element of quantum enhanced metrology. This typically requires low-noise detection technology. Such a challenge can be circumvent…
Dissipative time crystal in a strongly interacting Rydberg gas
Xiaoling Wu, Zhuqing Wang, Fan Yang +6
The notion of spontaneous symmetry breaking has been well established to characterize classical and quantum phase transitions of matter, such as in condensation, crystallization or…
Cyclic nonlinear interferometry with entangled non-Gaussian spin states
Qi Liu, Tian-Wei Mao, Ming Xue +2
We propose an efficient nonlinear readout scheme for entangled non-Gaussian spin states (ENGSs) based on the intrinsic quasi-cyclic dynamics of interacting spin-1/2 systems. We foc…
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…
Controlling atomic spin-mixing via multiphoton transitions in a cavity
Ming Xue, Xiangliang Li, Wenhao Ye +3
We propose to control spin-mixing dynamics in a gas of spinor atoms, via the combination of two off-resonant Raman transition pathways, enabled by a common cavity mode and a bichro…
Manipulating synthetic gauge fluxes via multicolor dressing of Rydberg-atom arrays
Xiaoling Wu, Fan Yang, Shuo Yang +4
Arrays of highly excited Rydberg atoms can be used as powerful quantum simulation platforms. Here, we introduce an approach that makes it possible to implement fully controllable e…
Persistent atomic spin squeezing at the Heisenberg limit
Ling-Na Wu, Meng Khoon Tey, L. You
Two well-known mechanisms, one-axis twisting (OAT) and two-axis countertwisting (TACT), generate spinsqueezed states dynamically. The latter provides better spin squeezing (SS) but…
