An international team of scientists from Australia, Japan and the United States, including our postdoc Rafael Alexander and UNM alum Nic Menicucci, has produced a prototype of a large-scale quantum processor made of laser light.

Based on a design ten years in the making, the processor has built-in scalability that allows the number of quantum components—made out of light—to scale to extreme numbers. The research was published in Science recently.
