Probing quantum entanglement from magnetic-sublevels populations: beyond spin squeezing inequalities

2022 · arXiv (Cornell University)

Spin squeezing inequalities (SSI) represent a major tool to probe quantum entanglement among a collection of few-level atoms, and are based on collective spin measurements and their fluctuations. Yet, for atomic ensembles of spin-$j$ atoms …
