Atome, die Bausteine der Natur, können als äußerst präzise Messinstrumente eingesetzt werden. So wird beispielsweise seit den1960er Jahren unsere Zeit durch die innere Schwingungsfrequenz von Cäsium-Atomen definiert. In einer hochpräzisen Atomuhr wird die innere Schwingungsfrequenz der Atome gemessen und in einen Sekundentakt umgewandelt. Diese Frequenz kann allerdings nicht mit beliebiger Genauigkeit bestimmt werden. Es gibt eine fundamentale Grenze der Genauigkeit durch das sogenannte Schrotrauschen. Dies sind grundsätzliche, statistische Schwankungen der Messwerte, die auftreten, wenn die Atome unabhängig voneinander schwingen.
