Lin Wang, Xichang Zhang, Konstantin Manannikov +4
Quantum light sources such as squeezed light are essential for quantum information science and technologies, but the scalable production of multiple beams of them remains a challen…
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…
Transit Noise in Spin Squeezing Experiments with Coated Rubidium Vapor Cell
Yujie Ji, Peiying Li, Yanhong Xiao +2
Spin squeezing can suppress quantum projection noise via interparticle entanglement, therefore enabling measurement sensitivities beyond the standard quantum limit. In practice, ho…
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…
Chirality-induced quantum nonreciprocity
Zimo Zhang, Zhongxiao Xu, Ran Huang +10
Chirality, nonreciprocity, and quantum correlations are at the center of a wide range of intriguing effects and applications across natural sciences and emerging quantum technologi…
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…
