Description
  • Quantum resistance metrology makes use of the quantum Hall Effect (QHE) to reproduce the unit of electrical resistance with unprecedented precision. Together with the unit of electrical voltage, based on the Josephson Effect, it allows the full space of all electrical quantities to be spanned. Following the forthcoming redefinition of the international system of units, SI, the kilogram, unit of mass, will also rely on the QHE for its reproduction. However, up to now the complexity of quantum standards precludes widespread use and necessitates a hierarchy of secondary standards to disseminate the electrical quantities to end-users. A simpler to use primary standard of electrical resistance, short-cutting tedious present-day calibration chains, is the key goal of this JRP.
