Multiparameter quantum metrology using strongly interacting spin systems
Min Jiang, Yunlan Ji, Qing Li +3
Interacting quantum systems are attracting increasing interest for developing precise metrology. In particular, the realisation that quantum-correlated states and the dynamics of i…
Machine-learning-assisted electron-spin readout of nitrogen-vacancy center in diamond
Peng Qian, Xue Lin, Feifei Zhou +5
Machine learning is a powerful tool in finding hidden data patterns for quantum information processing. Here, we introduce this method into the optical readout of electron-spin sta…
Calibration-Free Vector Magnetometry Using Nitrogen-Vacancy Center in Diamond Integrated with Optical Vortex Beam
Bing Chen, Xianfei Hou, Feifei Ge +7
We report a new method to determine the orientation of individual nitrogen-vacancy (NV) centers in a bulk diamond and use them to realize a calibration-free vector magnetometer wit…
Experimental Observation of Equilibrium and Dynamical Quantum Phase Transitions via Out-of-Time-Ordered Correlators
Xinfang Nie, Bo-Bo Wei, Xi Chen +8
The out-of-time-ordered correlators (OTOC) have been established as a fundamental concept for quantifying quantum information scrambling and diagnosing quantum chaotic behavior. Re…
Ultralow-field Nuclear Magnetic Resonance Asymmetric Spectroscopy
Min Jiang, Wenjie Xu, Yunlan Ji +3
Ultralow-field nuclear magnetic resonance (NMR) provides a new regime for many applications ranging from materials science to fundamental physics. However, the experimentally obser…
Time-optimal Control of Independent Spin-1/2 Systems under Simultaneous Control
Yunlan Ji, Ji Bian, Min Jiang +2
We derive the explicit solution of the problem of time-optimal control by a common magnetic fields for two independent spin- particles. Our approach is based on the Po…
