Qubits as Sensors

Several mega-trends of our age promise to shift the boundary of what we can measure and image. The building blocks of the quantum computer - single atoms, single molecules, single spins - can be used as novel sensors. They are the smallest measurement devices that have ever been built, and have enabled breakthrough results such as measuring the magnetic field of a single biomolecule. At the same time, modern signal processing and artificial intelligence can increasingly make sense of even weak and noisy signals like single photons.

Pushing this development is the mission of our group. We in particular aim to generate new methods for the life sciences.



Poster Prize for Mohammad Amawi


Congratulations to our PhD student Mohammad Amawi, who just won the prize for the best poster on the conference  "International AGYA Winter School: Quantum Materials for Energy and Environmental Applications" of the German-Arab Young Academy AGYA, hosted at the University of Sharjah (UAE)!



An MRI scan of single atoms


Our latest result just appeared in npj Quantum Information!

We have taken a three-dimensional image of single NV centers spins in a diamond by magnetic resonance tomography. We reach a resolution in the single-nanometer range, which can likely be pushed to the atomic scale in a future improved version of our nanoscale magnetic resonance scanner.

Teaching award


Our research group has won the award for excellence in teaching of the Faculty of Mathematics and the Sciences! This in particular highlights our class "Atomic Physics for Future Teachers" where some homework exercises are experiments with every-day items. 


First publication


The first paper produced in the new lab is out! We present a simple scheme to calibrate quantum control pulses, which is useful for many applications, especially for experiments on NV centers in diamond. You can learn more about it in AIP Advances 13, 035226 (2023)

Zeiss Quantum Challenge Award


A proposal of our group has won the quantum challenge of the optics company Zeiss. We propose to shrink a magnetic resonance imaging scanner to the size of a single biological cell, using NV centers in diamond as a microscale detector. The Quantum Challenge recognizes realistic and promising proposals for near-term applications of quantum technology. The award will also help to attract funding to pursue this project at the University of Rostock. Thanks to Zeiss for supporting our work in this way!
