The Wolfgang Wernsdorfer Lab

Karlsruhe Institute of Technology | 📍 Germany | 🔬 Physics
The Wernsdorfer Lab investigates quantum phenomena in magnetic systems at the atomic and molecular scale, with a strong focus on molecular nanomagnets, single-molecule magnets, and hybrid quantum platforms. The group aims to understand and control spin dynamics, quantum coherence, and relaxation processes in individual molecules and engineered nanostructures, bridging fundamental physics and emerging quantum technologies. A central research theme is the study of molecular spins as building blocks for quantum information science. This includes single-molecule magnets, toroidal magnetic states, and molecular qudits, where the lab explores how molecular structure, symmetry, and environment influence coherence times and quantum control. Another major direction involves coupling molecular spins to superconducting circuits and resonators, enabling hybrid quantum systems that combine chemical tunability with scalable solid-state platforms. Experimentally, the lab employs state-of-the-art techniques such as micro-SQUID magnetometry, electron spin resonance combined with scanning tunneling microscopy (ESR-STM), circuit quantum electrodynamics, and low-temperature transport and spectroscopy. These methods allow manipulation and readout of individual spins, vortices, and quantum states with high precision. The Wernsdorfer Lab is well suited for students with strong interests in condensed matter physics, quantum physics, or nanoscience. Ideal candidates are curious about quantum coherence and spin phenomena, enjoy hands-on experimental work at low temperatures, and are motivated to contribute to the development of future quantum technologies.
