Abstract
We propose a multisetting protocol for the detection of two-body Bell correlations, and apply it to spin-nematic squeezed states realized in pairs of SU(2) subsystems within spin- atomic Bose-Einstein condensates. Experimental data for , alongside with numerical simulations using the truncated Wigner method for , demonstrate the effectiveness of the proposed protocol. Our findings extend the reach of multisetting Bell tests in ultracold atomic system, paving the way for extended quantum information processing in high-spin ensemble platforms.
