Generalized spin squeezing inequalities in qubit systems: theory and experiment
J. K. Korbicz, O. Gühne, M. Lewenstein +3
We present detailed derivations, various improvements and application to concrete experimental data of spin squeezing inequalities formulated recently by some of us [Phys. Rev. Let…
