Neuartige Lichtquellen für die abhörsichere Telekommunikation

Photonen auf Bestellung

(PresseBox) (Stuttgart, )
Eine Lichtquelle, die nur ein Photon innerhalb eines kurzen Zeitintervalls emittiert, ermöglicht zahlreiche neue Anwendungen auf dem Gebiet der Quanten-Informationstechnologie. Dazu zählen insbesondere die Entwicklung abhörsicherer Datennetze sowie Konzepte für das optische Quantencomputing. Mit modernen Herstellungsverfahren und experimentellen Untersuchungen tragen das 3. Physikalische Institut und das Institut für Halbleiteroptik und Funktionelle Grenzflächen der Universität Stuttgart maßgeblich zur Erforschung und Realisierung derartiger Lichtquellen bei. Das Bundesforschungsministerium fördert diese Arbeiten innerhalb eines Forschungsverbundes an der Universität Stuttgart mit 867.000 Euro für drei Jahre.

Solche neuartigen Lichtquellen - Fachleute bezeichnen diese als quantisierte Lichtzustände - erlauben Funktionen, die mit klassischen Lichtzuständen nicht möglich ypqg.
