Quantum sensors made from diamond defects to let US scientists probe the universe

U.S. researchers at Argonne National Laboratory have launched a $1 million, three-year project to build quantum sensors from tiny flaws in diamonds called nitrogen-vacancy centers. These defects respond to electromagnetic fields, making them extremely precise measuring tools. The sensors could be integrated into particle accelerators, withstand high radiation, and help scientists explore fundamental questions about the universe with greater accuracy than ever before.
