Welcome to the Quantum Sensing Lab

Our laboratory is located in the Department of Physics of the University of Basel in Switzerland. Our research is centered around the emerging field of "Quantum sensing", where the use of individual, well-controlled quantum systems as high-performance sensing devices is being explored. We concentrate on implementing various types of such sensors and on applying them to outstanding scientific tasks in mesoscopic physics, nano-science and technology. At the moment, our quantum system of choice for these purposes is the Nitrogen-Vacancy (NV) color center in diamond, whose exceptional quantum-coherent properties allow for high-performance sensing applications (such as single-electron spin detection) even at room temperature.

Sigurd's Raman paper published on the arXiv!

Raman lasers based on bulk diamond are a valuable resource for generating coherent light in wavelength regimes where no common laser diodes are available. Nevertheless, the widespread use of such lasers is limited by their high threshold…

Welcome Tobias!

We welcome Dr. Tobias Sjölander to the group, good to have you! To successful experiments!

Congratulations Dr. Sigurd Flågan!

Sigurd successfully defended his thesis!

Annual Group Hike 2021: Aletsch Gletscher

This year's group hike featured the beautiful Aletsch glacier, a over-night stay at Villa Cassel and dangerous adventures atop swindling heights at the Seilpark! Stay tuned for future group events!
PhD Games

Congratulations Dr. Natascha Hedrich!

Natascha successfully defended her thesis!

Viktoria's laser writing paper published in ACS Photonics!

We report on pulsed-laser induced generation of nitrogen-vacancy (NV) centers in diamond facilitated by a solid-immersion lens (SIL). The SIL enables laser writing at energies as low as 5.8 nJ per pulse and allows vacancies to be formed…

Jodok's NV photophysics paper published on the arXiv!

We investigate the magnetic field dependent photo-physics of individual Nitrogen-Vacancy (NV) color centers in diamond under cryogenic conditions. At distinct magnetic fields, we observe significant reductions in the NV photoluminescence…

Goodbye Johannes!

We say goodbye to Dr. Johannes Kölbl after an excellent PhD and PostDoc! Thanks for everything and all the best at Sensirion!

Welcome Juanita!

A warm welcome to our new PostDoc, Juanita Bocquel! Good to have you and to successful experiments!

Natascha's domain wall paper published in Nature Physics

Antiferromagnets can encode information in their ordered magnetic structure, providing the basis for future spintronic devices1,2,3. The control and understanding of antiferromagnetic domain walls, which are the interfaces between domains…
