Scientists from the United States, Portugal and the United Kingdom have published a study that talks about the possibility of easing the requirements of ray tracing for iron through quantum computing. Productivity can increase up to 190%. This process is accomplished by limiting the number of computations required for each beam.
Earlier upscalers like DLSS, FSR 2.0, and XeSS have already begun to help improve ray tracing performance, but they do so by reducing the number of rendered image pixels and then increasing the output image. Quantum ray tracing does not require any upscaling and is applied to the image at native resolution, but uses an optimized tracing process to reduce the number of ray crossings calculated.
Everything is shown on an example image with a resolution of 128 by 128 and three ray tracing techniques. The classic version calculates 2,678,000 intersections for 41,842 rays. The unoptimized quantum rendering is 1,366,000 intersections, while the optimized one is only 896,000 intersections. The results are certainly impressive, but the technology, unfortunately, is still far from being accessible to ordinary users due to the lack of cheap quantum computing power on the market.
