Magnetisches Nanoschachbrett baut sich von selbst zusammen

Forscher schalten Quanteneigenschaften magnetischer Moleküle

(PresseBox) (Villigen PSI, )
Forscher des Paul Scherrer Instituts und des Indian Institute of Science Education and Research (Pune/Indien) haben in einer Anordnung magnetischer Moleküle gezielt den Magnetismus in jedem zweiten Molekül "abschalten" können, so dass ein magnetisches Schachbrettmuster entstand. Die magnetischen Moleküle wurden so konstruiert, dass sie von selbst ihren Platz im Nanoschachbrett finden. Damit baut sich das Nanoschachbrett von selbst zusammen. Die Forscher konnten gezielt den Quantenzustand eines Teils der Moleküle manipulieren. Die Möglichkeit, die Zustände einzelner Quantenobjekte gezielt zu verändern, ist eine wichtige Voraussetzung für die Entwicklung von Quantencomputern. Solche Computer nutzen die Gesetze der Quantenphysik und können manche Rechenaufgaben sehr
