MA 15: Focus Session: Quantum Sensing with Solid State Spin defects I (joint session TT/MA)

Tuesday, March 10, 2026, 09:30–12:45, HSZ/0003

The electron spins of defects in solid state materials show remarkable quantum coherence, making them excellent sensors. Recent advances in material engineering and measurement techniques lead to continuous improvements in the sensitivity and resolution of established single spin sensors such as the Nitrogen-Vacancy center in diamond, and the development of new defect sensors in materials such as Silicon Carbide and hexagonal Boron Nitride. In condensed matter physics, such sensors are often being used for exploring the structure of magnets, superconductors, topological phases, etc. This focus session will highlight most of the recent experimental and theoretical advances, current challenges, and emerging directions, focusing both on the improvements of the defects themselves, and their use for exploring novel phenomena in condensed matter physics.
