Weltrekord: Jülicher Forscher simulieren Quantencomputer mit 46 Qubits

(PresseBox) (Jülich, )
Wissenschaftler des Jülich Supercomputing Centre haben gemeinsam mit Forschern der Universitäten in Wuhan und Groningen einen neuen Weltrekord aufgestellt. Ihnen gelang es erstmals, einen Quantencomputer mit 46 Quantenbits, kurz: Qubits, zu simulieren. Für ihre Berechnungen nutzten sie den Jülicher Superrechner JUQUEEN sowie den derzeit weltweit schnellsten Superrechner Sunway TaihuLight am chinesischen National Supercomputing Center in Wuxi.

Wenn künftig die ersten praktisch anwendbaren Quantencomputer verfügbar sein werden, müssen Software-Entwickler und Ingenieure nicht bei Null anfangen. Auf herkömmlichen digitalen Computern lässt sich bereits heute die Funktionsweise relativ großer Quantenrechner simulieren. Der Rechenaufwand ist allerdings enorm. Mit jedem simulierten Quantenbit – kurz:
