Pioneering Quantum Sensing: The Foundation of Qnami Quantilevers
Patrick Maletinsky and his team at the University of Basel have developed a groundbreaking approach to harnessing nitrogen-vacancy (NV) centers in diamond for ultra-sensitive nanoscale magnetic sensing. In this work, they provide a comprehensive review of the fabrication and integration of nitrogen-vacancy (NV) centers in diamond. This work outlines optimized methods for creating single-crystal, all-diamond scanning probes.
By detailing the fabrication of diamond nanopillar probes and their efficient light extraction properties, the review highlights the robustness and effectiveness of these structures for scanning probe applications. As a demonstration, the team images the stray field of a single Ni nanorod, illustrating the achievable spatial resolution.
This foundational work serves as the basis for Qnami Quantilevers, state-of-the-art quantum sensors that enable highly precise and non-invasive magnetic field measurements at the nanoscale.
