AC-DC Difference

The NIST ac-dc Difference Project provides U.S. industry with the essential link between ac and the corresponding dc electrical standards via a world-class

Applications of Quantum Information

Theory is being developed and used to devise methods for preserving and exploiting the quantum behavior of ever-larger systems for metrology, communication, and

Calibration of Force Transducers

NIST provides calibration services for force-measuring instruments by applying known forces, compression, tension or both, to the elastic transducer and

Calibration of Mass Standards

NIST maintains the national standard for mass in the form of the prototype kilograms (K4, K20, K79, K92, and K102) and provides services to support the parts of

Electronic Kilogram

This project provides the basis for a new definition of mass, based on unchanging quantum properties of nature rather than a physical artifact. This is

Farad and Impedance Metrology

This project aims to provide the world's best basis for accurate impedance measurements by tying the U.S. legal system of electrical units to the International

High Resolution Atomic Spectroscopy

Accurate measurements of atomic wavelengths, energy levels, oscillator strengths and isotope and hyperfine structure using diffraction grating spectrographs

International System of Units (SI)

The International System of Units (SI) provides definitions of units of measurement that are widely accepted in science and technology and which set measurement

Memory

Critical to quantum information applications is the need to store a quantum state while other qbits are created or processed.

Metrology of the Ohm

Resistance standards traceable to NIST provide references for measurements of current at levels from 3000 A to below 20 fA and are used to support a wide

Plasma Metrology

Experimental and computational techniques in support of commercial and scientific uses of plasmas.

Precision Measurement Grants Program

Since 1970, the National Institute of Standards and Technology (NIST) has awarded Precision Measurement Grants for significant research in the field of

Quantum Biophotonics

Faint light detection is a staple in biology- used from systems biology research to bioassays for biomanufacturing and healthcare diagnostics.
