Field-Free Future: The Rise of Quantum Precision in Electronics
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 the Quantum Anomalous Hall effect.
The precise measurement of electrical resistance is essential in the industrial production of 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).
“With our new measurement method, we can significantly improve the accuracy of resistance measurements, without any external magnetic field, using the Quantum Anomalous Hall Effect (QAHE).”
