Leon Chao, a mechanical engineer at the National Institute of Standards and Technology (NIST), is developing new tools to support quantum measurement standards for mass and torque. Working within the Quantum Measurement Division, he focuses on building precision instruments like Kibble balances and torque realizers. These devices are designed to help establish accurate, quantum-based measurements that can serve as reliable reference points for calibration.
In collaboration with the Department of Defense, the current project aims to modernize metrology by creating commercially viable instruments for widespread use. The work is ongoing, with a specific focus on ensuring the technology meets rigorous requirements for adoption in commercial calibration laboratories. While no specific implementation date has been announced, the goal is to make these advanced quantum standards available to industries that require precise mass and torque measurements.
