Eine untrügliche Quantenmessung

(PresseBox) (Innsbruck, )
Für Quantenphysiker gehört die Verschränkung mittlerweile zum täglichen Handwerkszeug. Für den Bau von zukünftigen Quantencomputern bildet sie die wesentliche Grundlage. Nun haben Innsbrucker Forscher gemeinsam mit Schweizer Kollegen in der Fachzeitschrift Nature Physics eine neue, sehr verlässliche Methode zum Nachweis von Verschränkung veröffentlicht.

Quantencomputer, Quantenkommunikation und Quantenkryptografie sind ohne Verschränkung nicht denkbar. Für viele zukünftige Quantentechnologien bildet diese, für unser Alltagsverständnis seltsam erscheinende Eigenschaft von Quantensystemen die wesentliche Grundlage. Experimentalphysiker stehen daher heute in ihren Labors sehr häufig vor der Aufgabe, die Verschränkung in Quantensystemen eindeutig nachzuweisen.
