Quantum computers are expected to help in chemistry, but how exactly? In this episode, Alessandro Chiesa and Francesco Tacchino tell us about their recent work using IBM chips to predict results of neutron scattering experiments on magnetic molecules. A. Chiesa, F. Tacchino, M. Grossi, P. Santini, I. Tavernelli, D. Gerace & S. Carretta, Quantum hardware simulating four-dimensional inelastic neutron scattering, Nature Physics, March 2019 (paper, preprint)
