Researchers in Portugal, the US, and the UK recently published a paper in which they attempted to leverage quantum computing algorithms to optimize ray-traced rendering workloads. The researchers' approach helped cut intersections per ray in a scene by a factor of three. The use of older NISQ quantum computing technology meant rendering took several hours, however.
