Glasfaserkabel sind heute unverzichtbare Informationsleitungen für das Internet - nun dienen sie auch als Quanten-Labor. Das Atominstitut der TU Wien ist derzeit die einzige Forschungseinrichtung weltweit, an der einzelne Atome kontrolliert an das Licht in ultradünnen Glasfasern angekoppelt werden können. Spezielle Lichtwellen werden so präpariert, dass sie schon auf eine kleine Anzahl von Atomen sensibel reagieren. Damit lassen sich hochempfindliche Detektoren bauen, mit denen man winzige Stoffmengen nachweisen kann. Das Team um Professor Arno Rauschenbeutel, der eine von sechs Forschungsgruppen des Vienna Center for Quantum Science and Technology leitet, stellt seine Methode in der aktuellen Ausgabe des Fachjournals "Physical Review Aijrgqz" xit.
