Mar 31, 2016 · Quantum Measurement. The Quantum Measurement Division (QMD) provides the physical foundation for the International System of Units (Système International d'Unités or SI), colloquially referred to as the metric system.The division is currently heavily engaged in the redefinition of the SI that is expected to occur in 2018.

Feb 13, 2025 · Quantum computers need a "clean" workspace, and a team including scientists at NIST has found a way to make one.

NIST Calibrates Quartz Crystals for Fusion Device In addition to our mission to realize the Système International (SI) units for absorbed dose (the gray) and activity (the becquerel), we maintain an active research programs in terahertz spectroscopy, neutron physics, radiation dosimetry, and radionuclide metrology.

The Sensor Science Division (SSD) is based in Gaithersburg, Maryland, and operates within the Physical Measurement Laboratory at NIST. Our Vision is to be the primary driver for innovation in the SI-traceable measurement of dimensional, thermodynamic, optical radiation, fluid flow, and air speed quantities.
