Researchers use a technique called resonant inelastic X-ray scattering, or RIXS, to study the electronic behavior of quantum materials. The image above illustrates an ultrabright X-ray striking a quantum material’s electrons (gray circles) and scattering off the sample. In this example, the X-ray’s energy change will provide insight into an electron property called spin, represented by the arrows. 

From computer chips to image sensors in cameras, today’s technology is overwhelmingly based on a semiconductor called silicon. This technology has been shrinking for decades—think of early room-sized computers compared to today’s desktops—but physical limitations will soon prevent further improvement.

That’s why scientists and engineers are preparing for a new generation of technology, one based on quantum mechanics.
