NIST is developing quantum-based standards for voltage and current measurements to support emerging technologies in computing and communications. These standards will enable more accurate, miniaturized, and automated measurements in microelectronics, with applications in cellphones, pacemakers, and other devices. The new standards will also support the redefinition of the International System of Units (SI), particularly the new definition of the ampere, which has significant implications for the microelectronics industry and beyond.
