Eine frohe Botschaft macht die Runde: Bis 2025 wollen niedersächsische Forschende einen 50-Qubit-Quantencomputer realisieren. Aus diesem Grund besuchte der niedersächsische Wissenschaftsminister Björn Thümler am Montag Wissenschaftsstandorte sowohl in Hannover als auch die PTB in Braunschweig. Mit von der Partie waren die Präsidentin der TU Braunschweig Prof. Dr. Angela Ittel, PTB-Vizepräsident Dr.-Ing. Prof. h. c. Frank Härtig und Journalisten. Eingeladen hatte das Bündnis Quantum Valley Lower Saxony (QVLS), um die wichtigsten Quantentechnik-Laboratorien und beteiligte Wissenschaftlerinnen und Wissenschaftler vorzustellen. Minister Thümler lobte: „Niedersachsen ist in der Quantentechnologie aktuell ein Stück voraus. Mit Hilfe von QVLS sollen aus Science Fiction Science Facts werden.“

For the first time, physicists have succeeded in successfully realizing a new method for cooling protons using laser-cooled ions - in this case beryllium ions. The innovative feature of the new system is that the two particle types are located in spatially separated traps. This means it is now possible to provide the cooling effect with the help of an electrical resonant circuit over a distance of nine centimetres from one trap to the other. The team at the PRISMA+ Cluster of Excellence at Johannes Gutenberg University Mainz (JGU), part of the BASE collaboration, was able to demonstrate that protons can be cooled to significantly lower temperatures in one of the traps than would be possible without beryllium.
