Multisetting protocol for Bell correlated states detection with spin- systems
Arkadiusz Kobus, Xinwei Li, Mariusz Gajda +2
We propose a multisetting protocol for the detection of two-body Bell correlations, and apply it to spin-nematic squeezed states realized in pairs of SU(2) subsystems within sp…

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…

Boundary Time Crystals Induced by Local Dissipation and Long-Range Interactions
Zhuqing Wang, Ruochen Gao, Xiaoling Wu +4
Driven-dissipative many-body system supports nontrivial quantum phases absent in equilibrium. As a prominent example, the interplay between coherent driving and collective dissipat…
