Physical Measurement Laboratory Divisions

Applied Physics Division

Our mission is to advance measurement science & technology in areas of critical importance to national priority needs, such as, advanced manufacturing, national security, quantum communications, strategic computing, and quantitative imaging. Photonics, magnetics, and imaging are transformative

Office of Weights and Measures

NIST OWM establishes uniformity, equity, SI use, and traceability in weights and measures by advancing national and international legal metrology standards, procedures, capabilities, and training.

Quantum Measurement Division

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.

Quantum Physics Division

The Division performs collaborative experimental and theoretical research and innovation advancing fundamental measurement science through quantum information science, quantum-enhanced precision measurement, ultracold atoms and molecules, quantum many-body physics, chemical physics, biophysics, and

Quantum Sensors Division

The Quantum Sensors Division, part of NIST’s Physical Measurement Laboratory, advances the detection of photons and particles in a variety of application areas using superconducting sensors and readout electronics.

Radiation Physics Division

The Division develops, maintains and disseminates the national measurement standards for ionizing radiation and radioactivity, and methods and models to address related applications.

Sensor Science Division

The Division advances the measurement science, standards, and applications for dimensional, optical radiation, and thermodynamic quantities to support U.S. industry and trade. We maintain and disseminate standards for three of the seven SI base units: the kelvin (temperature), the meter (length)

Time and Frequency Division

The Time and Frequency Division maintains the standard for frequency and time interval for the United States, provides official time to the United States, and carries out a broad program of research and service activities in time and frequency metrology.
