Researchers at NIST, led by physicist Stephen Eckel, have developed the world’s first measurement standard for extreme vacuum pressure using cold-atom technology. This system uses ultra-cooled atoms to detect incredibly low levels of air with record-breaking accuracy. Previously confined to academic labs, the device is now a practical, field-ready tool that establishes a global benchmark for precision pressure sensing.
The standard is already implemented and will directly support the manufacturing and operation of quantum computers, which require near-perfect vacuums to keep delicate quantum states stable. By providing consistent, highly accurate vacuum measurements, this technology improves the reliability and quality control of quantum hardware. NIST plans to adapt the same cold-atom principles for future navigation and gravity-mapping systems that could create secure, hacking-resistant positioning tools. While the vacuum standard is currently in active use, these expanded applications remain in development with no fixed rollout dates yet.
