Researchers at the University of Würzburg have developed a method that can improve the performance of quantum resistance standards. It’s based on a quantum phenomenon called Quantum Anomalous Hall effect.
The precise measurement of electrical resistance is essential in industrial production or electronics - for example, in the manufacture of high-tech sensors, microchips and flight controls. "Very precise measurements are essential here, as even the smallest deviations can significantly affect these complex systems", explains Professor Charles Gould, a physicist at the Institute for Topological Insulators at the University of Würzburg (JMU). ...
