Physicists have confined electrons to the smallest circuits ever made and witnessed their strange behaviour. Scientists at Maximilians University in Munich and the University of California in Santa Barbara created an experiment with the smallest rings, or quantum dots, ever made to support measurable currents. Only 50 billionths of a metre across, the rings displayed strong quantum effects when they contained only one or two electrons. Scientists hope that quantum dots may be used as the basis for memory in quantum computers of the future.
