This article focuses on NIST's development of superconducting quantum sensors that utilize transition edge technology to precisely measure X-ray emissions from nuclear materials. By distinguishing between overlapping photon signals with unprecedented accuracy, this advancement directly enhances international safeguards and the accounting of nuclear stockpiles using core quantum sensing principles. The work represents a significant application of quantum metrology rather than a general consumer or software development story.
NIST quantum sensors help verify nuclear safeguards internationally
NIST developed quantum sensors to more accurately monitor nuclear material at power plants and weapons facilities, measuring X-ray emissions from plutonium, uranium and neptunium with unprecedented accuracy. These measurements support international nuclear safeguards by enabling more precise accounting of material in nuclear facilities.

Credit: NIST Researchers have achieved accuracy in measuring X-ray emissions from plutonium, uranium, and neptunium using an array of about 250 quantum sensors developed at NIST. This advance allows for more precise filtering of background noise that previously obscured accurate assessment of nuclear materials at power plants and weapons facilities. “Our measurements support international nuclear safeguards by enabling more precise accounting of material in nuclear facilities,” said Jonathan Dean, a physicist at NIST and the University of Colorado Boulder. By reducing…
