Manipulating individual electrons with the goal of employing quantum effects offers new possibilities and greater precision in electronics. However, these single-electron circuits are governed by the laws of quantum mechanics, meaning that deviations from error-free operation still occur—albeit (in the best possible scenario) only very rarely. Thus, insights into both the physical origin and the metrological aspects of this fundamental uncertainty are crucial for the further development of quantum circuitry. To this end, scientists from PTB and the University of Latvia have collaborated to develop a statistical testing methodology. Their results have been published in the journal Nature Communications.
