The Quantum Devices team of prof. Caspar van der Wal performs experimental research that focuses on the quantum physics of electron spin ensembles and nuclear spin ensembles in semiconductor devices. Current projects study electron spin manipulation and dephasing for ensembles, electron many-body effects, and quantum state transfer between spin states and optical pulses. Our work has a basis in expertise on conventional semiconductors such as GaAs, but we currently mainly explore new material systems such as color centers in wide-band-gap materials (e.g. SiC), 2D materials, and organic or hybrid organic-inorganic molecular systems. We use electron transport methods, optical pump-probe techniques and quantum optical techniques. While there is a clear link to application-driven research on quantum information technology and spintronics, our focus is on fundamental studies of quantum coherent dynamics in solid-state devices. See Research and Publications for more information.

The Quantum Devices team operates in the Physics of Nanodevices Group at the Zernike Institute for Advanced Materials of the University of Groningen, the Netherlands.

We contribute to education in Physics and Applied Physics, and the Top Master in Nanoscience of the Zernike Institute for Advanced Materials.
