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.","lang":"eng"}],"issue":"14","title":"Bell correlations in spin-squeezed states of 500 000 atoms"}
