Test of local realism via entangled $$\Lambda \bar{\Lambda }$$ system

M. Ablikim, M. N. Achasov, P. Adlarson, X. C. Ai et autres

The non-locality of quantum correlations is a fundamental feature of quantum theory. The Bell inequality serves as a benchmark for distinguishing between predictions made by quantum theory and local hidden variable theory (LHVT). Recent advancements in photon-entanglement experiments have addressed potential loopholes …
