Creation of 2000-atom Greenberger-Horne-Zeilinger states by entanglement amplification
Yajuan Zhao, Rui Zhang, Wenlan Chen +2
We propose a novel entanglement-creation scheme in a multi-atom ensemble, named entanglement amplification, which converts unentangled states into entangled states and amplifies le…
Vacuum spin squeezing
Jiazhong Hu, Wenlan Chen, Zachary Vendeiro +3
We investigate the generation of entanglement (spin squeezing) in an optical-transition atomic clock through the coupling to a vacuum electromagnetic field that is enhanced by an o…
Strictly nonclassical behavior of a mesoscopic system
Jiazhong Hu, Zachary Vendeiro, Wenlan Chen +4
We experimentally demonstrate the strictly nonclassical behavior in a many-atom system using a recently derived criterion [E. Kot et al., Phys. Rev. Lett. 108, 233601 (2012)] that…
Entangled collective-spin states of atomic ensembles under non-uniform atom-light interaction
Jiazhong Hu, Wenlan Chen, Zachary Vendeiro +2
We consider the optical generation and verification of entanglement in atomic ensembles under non-uniform interaction between the ensemble and an optical mode. We show that for a w…
