Enhancing collective spin squeezing via one-axis twisting echo control of individual atoms
Zhiwei Hu, Youwei Zhang, Junlei Duan +2
Spin squeezing generated via inter-atom entanglement in multilevel atomic ensembles provides a powerful resource for quantum-enhanced metrology. Existing schemes that harness inter…
Cooperative squeezing of internal and collective spins in an atomic ensemble
Youwei Zhang, Shenchao Jin, Junlei Duan +4
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…
