Multisetting protocol for Bell correlated states detection with spin-$f$ systems

Quantum Gases 2025-11-11 v3 Quantum Physics

Abstract

We propose a multisetting protocol for the detection of two-body Bell correlations, and apply it to spin-nematic squeezed states realized in ff pairs of SU(2) subsystems within spin-ff atomic Bose-Einstein condensates. Experimental data for f=1f=1, alongside with numerical simulations using the truncated Wigner method for f=1,2,3f=1,\,2,\,3, 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.
