Quantum electrodynamics (QED) is a cornerstone of the standard model of particle physics. A decade-long effort to simulate QED on a two-dimensional lattice has now succeeded — through the use of a trapped-ion quantum computer based on multidimensional ‘qudits’, which are uniquely suited to the challenge.
