Description
In recent years, growing attention has been devoted to the interface between collider physics and quantum information. A particularly intriguing direction is the exploration of quantum phenomena, such as entanglement, in high-energy scattering processes, including DIS at the EIC and ultraperipheral collisions at the LHC. In this context, we present the first study of spin--spin correlations in the exclusive production of a heavy quark--antiquark pair. We show that, in the Regge limit, the diffractive mechanism leaves a distinctive imprint on the quantum correlations of the final state: the produced $q\bar q$ pair is always entangled and exhibits a violation of the Bell--CHSH inequality.
