Quantum Measurement Division Groups

Welcome to the Applied Electrical Metrology Group

The mission of the Atomic Spectroscopy Group is to measure, calculate, critically compile, and disseminate reference data on atomic properties and fundamental constants in support of basic research, commercial development, and national priorities.

The Fundamental Constants Data Center is focused on physics relevant to the determination of values of the fundamental constants of physics and chemistry.

The Fundamental Electrical Measurements group supports the nation's infrastructure by providing calibration services in the general areas of resistance and impedance. As part of this mission, the group maintains an active research program in precision measurements based on fundamental constants in

We use ultracold gases and other atomic systems to study quantum phenomena including many-body physics, superfluidity, and quantum information.

The Group provides traceability for the SI units of mass and force, measurement services, and research in support of the U.S. industry, government, and scientific community.

Our group studies and develops techniques relying on quantum optics and quantum optics-based components for new measurement capability, improved metrological accuracy, and quantum information applications.
