Atomic defects in diamonds can be used as quantum memories. Researchers at TU Wien for the first time have succeeded in coupling the defects in various diamonds using quantum physics.
Designing alloys to withstand extreme environments is a fundamental challenge for materials scientists. Energy from radiation can create imperfections in alloys, so researchers in an Energy Frontier Research Center led by the Department of Energy’s Oak Ridge National Laboratory are investigating ways to design structural materials that develop fewer, smaller flaws under irradiation. The key, they report in the journal Nature Communications, is exploiting the complexity that is present when alloys are made with equal amounts of up to four different metallic elements.
