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…

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…
