This first technical note (download here directly) aims to provide the reader with the fundamentals of NV magnetometry. In a first part we introduce the nitrogenvacancy (NV) center and its fundamental properties. In the second part we show how the NV center is used to measure magnetic fields with unprecedented sensitivity.
The quantum physics explained in this note are the core principles behind our Qnami ProteusQ Scanning NV Magetometer microscope, as well as our Quantilever series of sensors and probes.
Qnami ProteusQ is a complete quantum microscope system. It is the first scanning NV (nitrogen-vacancy) microscope for the analysis of magnetic materials at the atomic scale. The Qnami ProteusQ system comes with state-of-the-art electronics and software. Its flexible design allows for future adjustments and scaling, expansion and capability upgrades. The proprietary Qnami ProteusQ quantum technology provides high precision images for you to see directly the most subtle properties of your samples and the effect of microscopic changes in your design or fabrication process.
About Qnami: Qnami is a VC-backed high-tech company with its roots at the Physics Department of the University of Basel in Switzerland. It develops fundamental new technology using quantum mechanics. The control of the state of a single electron enables measurement with a precision that could never be achieved before. The technique is called quantum sensing and Qnami is enthusiastically developing it to improve people’s lives and the world. Extensive academic research and deep knowledge build the ground for all that Qnami does. With this technology, Qnami is redefining the common understanding of precision.
