A schematic picture of a metal surface used in, for example, advanced detectors or quantum computers. New analysis has found that the excess noise levels seen in metal surfaces is caused by the thermal vibration of impurity atoms adsorbed onto the surface, shown here as purple arrows. (The green ball represents an ion - part of the electrical device's operational mechanism - that has been intentionally placed on the surface.
