QSA scientists have advanced major quantum computing technologies based on superconducting qubits, trapped ions, and neutral atoms.  These different technologies can be applied in quantum science to study fundamental phenomena and advance new materials. The scientific and technological progress in materials physics led by QSA facilitates the understanding and design of novel properties in superconductors, quantum spin liquids, magnetism, and topological materials.

A technique called resonant inelastic X-ray scattering, or RIXS, is particularly suited for probing samples as thin as one atomic layer and material states that change very rapidly. With recent technological developments, researchers expect this technique to enable studies that were unthinkable only five years ago. This progress gave Mark Dean and three colleagues — Matteo Mitrano, Steven Johnston, and Young-June Kim — the impetus to chart where the field is going as a whole. So, they summarized the technique’s state of the art and how they expect the field to progress in a Perspective paper, recently published in Physical Review X.

Argonne National Laboratory announced Xander Newlun from the University of Texas at San Antonio won the 2025 Conquer the Hill® Command competition.

A workshop led by scientists at ORNL sketched a road map toward a longtime goal: development of autonomous, or self-driving, next-generation research laboratories. 

Jefferson Lab’s heating, ventilation and air conditioning professionals ensure optimal operation of operational and scientific facilities through their technical expertise.

Relying on leading-edge germanium detectors developed by researchers at the Department of Energy’s Oak Ridge National Laboratory, the scientific community pursues elusive nuclear processes to unlock persistent mysteries. Answers to questions they hope to resolve hold the potential to redefine the universe itself. 

What is of quantum coherence and how it is used for quantum sensing and quantum computing applications?

On 12 February, the CEA’s WEST machine was able to maintain a plasma for more than 22 minutes. In doing so, it smashed the previous record for plasma duration achieved with a tokamak. This leap forward demonstrates how our knowledge of plasmas and technological control of them over longer periods is becoming more mature, and offers hope that fusion plasmas can be stabilised for greater amounts of time in machines such as ITER.
