Improving the signal-to-noise ratio in quantum chromodynamics simulations: A new simulation method enables more precise simulation for ensembles of elementary particles

A study describes a new technique for simulating particle ensembles that are 'large' (at least by the standards of particle physics). The technique improves the signal-to-noise ratio and thus the precision of the simulation; crucially, it can also be used to model ensembles of baryons: a category of elementary particles that includes the protons and neutrons that make up atomic nuclei.
