The Researchers can use the heating furnace to improve the NF Lab provides the researchers with the clean environment properties of components from the quantum sciences, such they need in order to produce these samples. as silicon-germanium qubits or quantum sensors based on nitrogen-vacancy centers in diamonds. Over the last year, the Quantum Sensing group led by Pro- fessor Patrick Maletinsky (Department of Physics) made inten- sive use of the NF Lab in order to produce and further optimize nanoscale quantum sensors, whose principal application is in “The team of the Nano Fabrication qualitative magnetic imaging on the nanoscale. For example, Lab is invaluable for our research at the sensors are used in the development and improvement of the interface between quantum and novel magnetic storage media for computer applications and to nanotechnology. They not only ensure analyze interesting new magnetic materials.
