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…
