Creating highly spin-squeezed states for quantum metrology surpassing the standard quantum limit is a topic of great interest. Spin squeezing has been achieved by either entangling…
Concurrent spin squeezing and light squeezing in an atomic ensemble
Shenchao Jin, Junlei Duan, Youwei Zhang +7
Squeezed spin states and squeezed light are both key resources for quantum metrology and quantum information science, but have been separately investigated in experiments so far. S…
Machine Learning Assisted Vector Atomic Magnetometry
Xin Meng, Youwei Zhang, Xichang Zhang +6
We propose a novel paradigm to vector magnetometry based on machine learning. Unlike conventional schemes where one measured signal explicitly connects to one parameter, here we en…
Retrodiction beyond the Heisenberg uncertainty relation
Han Bao, Shenchao Jin, Junlei Duan +4
In quantum mechanics, the Heisenberg uncertainty relation presents an ultimate limit to the precision by which one can predict the outcome of position and momentum measurements on…
Sub-Hertz resonance by weak measurement
Weizhi Qu, Jian Sun, Shenchao Jin +3
Weak measurement (WM) with state pre- and post-selection can amplify otherwise undetectable small signals and thus promise great potentials in precision measurements. Although freq…
Measurements with prediction and retrodiction on the collective spin of 10^{11} atoms beat the standard quantum limit
Han Bao, Junlei Duan, Xingda Lu +10
Quantum probes using uncorrelated particles give a limit on the measurement sensitivity referred to as the standard quantum limit (SQL). The SQL, however, can be overcome by ex…
