Description
Entanglement offers a compact and quantitative way to characterize correlations in quantum many-body systems, and can therefore provide new information on nuclear structure beyond standard observables. In this talk I discuss how quantum-information concepts—focusing on spin entanglement—can be connected to few-body nuclear dynamics, with emphasis on two-proton emission. Motivated by recent theoretical predictions of Bell–CHSH inequality violation in the unbound nucleus 6Be, I outline how the decay 6Be →α+p+p can serve as a sensitive probe of proton–proton correlations and decay mechanisms. I also summarize the experimental perspective at R3B/GLAD, where full reconstruction of charged fragments and downstream proton polarimetry can enable access to spin observables and entanglement-related signatures.
