From the article, it mentions measuring temperature fluctuations at the "nanoscopic" level as well as studying friction between two materials on much smaller scales. This is pretty cutting edge stuff, from the article: "For starters, scientists don’t know precisely how to make the S3 defect centers. Current techniques rely on growing diamonds with a nickel precursor and hoping the defects show up." I'm sure as the technique is refined and understood, more applications will arise.
Any realistic uses though?
