Nano and quantum technologies for the ion trap based quantum computers from Lower Saxony

The Quantum Valley Lower Saxony (QVLS) bundles Lower Saxony's science and industry in the field of quantum technologies. The Minister President of Lower Saxony, Stephan Weil, together with representatives of the press, now visited the QVLS at Leibniz University Hannover. The main topic of the lab tour was the production and research of ion trap based quantum computers.

The tour started with a visit to the laser laboratories of the research groups "Molecular Quantum Gases" and "Quantum Engineering with Trapped Ions" in the Welfenschloss. Afterwards, the technical possibilities in the clean room for the production of components for quantum technologies were shown in the research building of the Laboratory of Nano and Quantum Engineering. In addition, Braunschweig partners of the QVLS presented selected quantum technology demonstrators.

In the clean room of the research building of the Laboratory of Nano and Quantum Engineering there is a complete semiconductor process line with oxidation, metallization, photo and electron beam lithography, etching, ion implantation, as well as extensive analysis capabilities. The cleanroom tour explained these key semiconductor fabrication process steps, which are also used to produce the ion-based quantum chips that are the heart of quantum computing. In particular, a new facility for selective laser-induced etching, which is currently being set up specifically for the production of quantum chips, was presented. 

Minister President Stephan Weil was visibly impressed by the technological equipment and in particular the enthusiasm of the researchers for nano and quantum technologies.
