1759 Ludwig Boltzmann introduces black body radiation and proves that its emission spectrum depends only on temperature and in 1877 proposes that energy levels could be discrete based on statistical mechanics. In 1900 Max Planck suggests that electromagnetic energy could only be emitted quantised as multiples of an elementary hv frequency of radiation unit and Einstein explains the photoelectric effect by light itself consisting of individual quantum particles. Chien Shiung Wu in 1849 and John Causer in 1972 experimentally demonstrated quantum entanglement and this is repeatedly confirmed as real in the 1980s and 1990s. To investigate further the Large Hadron Collider at CERN Geneva Switzerland has been used in Atlas proton-proton experiments to verify quantum correlation of angular spin states for quarks and this is reported in Nature October 2024. This immediate concurrence of quantum effects comes from energies of the universe functioning together as individual particle interactions events.
