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…
Joint Estimation of a Two-Phase Spin Rotation beyond Classical Limit
Jiahao Cao, Xinwei Li, Tianwei Mao +2
Quantum metrology employs entanglement to enhance measurement precision. The focus and progress so far have primarily centered on estimating a single parameter. In diverse applicat…
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…
Nonlinear interferometry beyond classical limit facilitated by cyclic dynamics
Qi Liu, Ling-Na Wu, Jia-Hao Cao +5
Time-reversed evolution has substantial implications in physics, including prominent applications in refocusing of classical waves or spins and fundamental researches such as quant…
