Here, we demonstrate Bell correlations in squeezed states of 5×105 Rb87 atoms. The correlations are inferred using collective measurements as witnesses and are statistically significant to 124 standard deviations. The states are both generated and characterized using optical-cavity aided measurements."}],"status":"public","publication_status":"published","publist_id":"7212","type":"journal_article","publisher":"American Physical Society","citation":{"ieee":"N.
