Researchers at the University of Ottawa and Federico II University in Italy created a programmable light simulator that can mimic how particles move through complex materials without needing bigger electronic hardware. They used three special screens to shape the light and ran over 300 different quantum processes. The simulator can also study exotic phases of matter.

A team of researchers at the University of Ottawa and its Nexus for Quantum Technologies Institute, in collaboration with researchers from Federico II University in Italy, has developed a programmable quantum simulator that shapes a beam of light to replicate how particles move through complex materials. This innovation avoids the need for ever-larger electronic hardware.

The researchers used three programmable optical screens called spatial light modulators to carefully sculpt the spatial pattern and polarization of photons so they evolve in the same way electrons would inside a crystal. A simple software update is all it takes to reconfigure the entire experiment for a new simulation.

The team validated the platform with both classical laser light and individual photons, running more than 300 distinct quantum processes and spreading a single input beam across thousands of output channels. In one set of experiments, the simulator reproduced the telltale signatures of topological materials, exotic phases of matter whose internal geometry protects electrons from disturbances.

The system's reach extends well beyond flat grids. By reprogramming the optical patterns, the same setup simulates particle motion on closed loops, cylinders and doughnut-shaped surfaces, geometries that capture features of advanced quantum materials.
