报告摘要:While quantum teleportation is a cornerstone of modern quantum information science, its realization within nuclear systems has remained largely unexplored. Here, using proton-proton scattering as a quantum laboratory, we report the emergence of a Bell-transition operator at a laboratory energy of 151 MeV and a center-of-mass scattering angle of 90 degrees, driven by a three-fold coincidence in strong interaction dynamics. Building upon this emergent resource, we propose a quantum teleportation protocol for proton spins, exploiting the intrinsic Hamiltonian of the strong interaction to perform the requisite Bell measurement. These findings effectively bridge few-body nuclear physics and quantum technology, establishing proton-proton scattering as both a source of high-fidelity entanglement and a natural processor for quantum information.
