QMAT — Quantum Sensors for Physical Material Science
The project develops a low-temperature, high-magnetic-field scanning quantum microscope based on NV-center quantum sensors to investigate local material properties at the 2D interface. By using multiple and entangled NV centers, the sensitivity, spatial resolution, and accessible frequency range are significantly improved. The technology enables, for the first time, the visualization and analysis of vortex dynamics in 2D superconductors, thereby creating a powerful new tool for the study of quantum materials.
he project develops a measurement platform for quantum sensing aimed at material analysis at sub-Kelvin temperatures and high magnetic fields (up to 1 T). The goal is to extend spin-based quantum microscopy, in which single or few atomic sensors detect local magnetic and electronic properties of materials, to extreme measurement conditions.
To achieve this, NV centers in diamond are stabilized at very low temperatures, their coherence times are improved, and material properties as well as surface treatments are optimized. These developments will enable reliable, high-resolution measurements for materials science applications.
By achieving the stated objectives, new application areas for quantum technologies will emerge through the experimental characterization and theoretical simulation of novel materials. The goal is to bring a new quantum sensing tool to the market that can make key contributions to the research and development of emerging quantum technologies.
