Neue Ergebnisse in der Quantenphysik: Zugang zur Quantentechnologie wird einfacher

(PresseBox) (Wien, )
In Rahmen einer internationalen Kooperation sind PhysikerInnen der Universität Wien robusteren Quantentechnologien einen weiteren Schritt näher gekommen: Sie haben gezeigt, dass für essenzielle Operationen in der Quanteninformationsverarbeitung weniger empfindliche Ressourcen verwendet werden können. "Die von uns gezeigten Quanteneffekte können zur Entwicklung verbesserter Informations- oder Computersysteme beitragen", so der Quantenphysiker der Universität Wien Philip Walther. In einem in "Nature Physics" publizierten Experiment demonstrieren die WissenschafterInnen, dass die für zukunftsträchtige Quantentechnologien wesentliche Fern-Herstellung von Quantenzuständen auch ohne Verschränkung möglich ist.

Eine wesentliche Eigenschaft in der Quantenphysik ist, dass zwei oder mehrere Quantenteilchen stärker als klassisch möglich miteinander verbunden, d.h. korreliert, sein
