Entangled collective-spin states of atomic ensembles under non-uniform atom-light interaction [PDF]

open access: yes, 2015
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 wide range of parameters a system of non-uniformly coupled atomic spins can
