Stabile Quantenbits

Experiment bestätigt Modell des Dortmunder Physikers Uhrig

(PresseBox) (Dortmund, )
Bereits 2007 hat der Physiker Prof. Dr. Götz S. Uhrig, Inhaber der Lehrstuhls für Theoretische Physik I an der TU Dortmund, eine Methode ersonnen, wie die fragilen Zustände von Quantenbits möglichst lange stabil gehalten werden können. Seine theoretisch in Formeln beschriebene Optimierung konnte bislang jedoch noch nicht experimentell bestätigt werden. Jetzt haben amerikanische Wissenschaftler des National Institute for Standards and Technology (NIST) das Modell ihres Dortmunder Kollegen im Experiment überprüft. In der neusten Ausgabe von Nature berichten sie, wie sie mit Hilfe einer von Uhrig errechneten Folge von Laserpulsen gezielt angeregte Zustände in Atomkernen über einen wesentlichen längeren Zeitraum als zsbhuo qyhgxog nlvmuhpo ssrrrzup jxnbhab.
