This will lead to a significantly reduced measurement uncertainty for ac resistanc… Project Programmable graphene resistance standards The project will develop and test programmable resistance standards of graphene. Project Realization of electrical resistance in alternating current The project has developed measurement systems and graphene samples for the realization of electrical resistance in alternating current and impedance using the Quantum Hall Effect. Using the new methods the calibration of standards… Story Developing Quantum Metrology – and Metrology for Quantum Technology Quantum mechanics has long been a natural part of metrology and has already revolutionised how we measure and realize physical units. The development of quantum technology is rapid which create opportunities for new measuring inst… Expertise Quantum Technologies We are now at the beginning of the second quantum revolution, promising a scientific and industrial paradigm shift where we will be able to quickly develop new drugs, secure communication and navigate without GPS with unprecedente… Expertise Electric voltage Electric dc voltage is an area of expertise at the National Measurement Laboratory for Electrical Quantities. We realise the unit related to electrical potential difference (voltage), volt, by utilizing the Josephson effect. … Expertise The National Laboratory for Electrical Q RISE is Sweden's NMI (National Metrology Institute) and is, according to the Swedish constitution, responsible for the fundamental measurement quantities in the International System of Units, SI. Expertise The National Laboratory for Mass RISE is the National Metrology Institute of Sweden and is responsible, through its National Laboratories, for the fundamental measurement quantities in the International System of Units (SI). Expertise Electrical resistance Electrical resistance is an area of expertise at the National Measurement Laboratory for Electrical Quantities. At our laboratory the resistance unit is realised with the highest possible accuracy. In addition…
