We present the prospects of detecting quantum entanglement and the violation of Bell inequalities in events at the LHC. We first introduce suitable observables and then perform an analysis using simulated events in the dilepton final state, up to the unfolded level. We find that entanglement can be easily established at better than both at threshold as well as at high- already in the LHC Run 2 dataset. On the other hand, only very high- events are sensitive to a violation of Bell inequalities, making it significantly harder to observe experimentally, even at the end of the LHC High Luminosity Run.
