摘要：

Optically pumped magnetometers are highly sensitive devices at the forefront of international quantum-sensing initiatives. In this talk, I will present our color-center–based sensing projects, with a particular focus on our efforts to detect neuronal action potentials using a diamond endoscope developed within the BMFTR-funded quantum-sensing lighthouse project DIAQNOS.

DIAQNOS—Diamond Quantum Sensing for Neurosurgery—is a collaborative initiative between quantum physicists across Germany and neurosurgeons at the University Clinic Freiburg. Its goal is to translate the impressive performance of quantum sensors in the laboratory into the neurosurgical operating theater, where they could support diagnostics, enhance neuronavigation, and ultimately improve patient outcomes.

报告人简介：

Dr. Arne Wickenbrock is the Deputy Section Leader of Matter–Antimatter Asymmetry, Gesellschaft für Schwerionenforschung Darmstadt, Helmholtz Institute Mainz. His research interests are mainly in quantum sensing and precision measurement, with a particular focus on spin-based sensors and nitrogen-vacancy centers in diamond.

Dr. Wickenbrock has made important contributions to microwave-free and high-sensitivity diamond magnetometry, as well as zero- and ultralow-field magnetic resonance. His research also explores applications of quantum sensors in fundamental physics, including searches for axion-like dark matter, and in biomedical sensing. He has published extensively in high-profile journals including Nature Physics, Nature Communications, Science Advances, etc.
