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)

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!

We have developed a new scheme to read out NV centers. It is much faster than what has been possible before - up to a factor of 1000 in some applications. The key trick is to employ the NV center itself as a single-atom flash memory. Using a resonant spin-charge conversion protocol at cryogenic temperature, we write the spin state of the NV center into this memory, where it can be read out very efficiently by fluorescence.

Imaging of action potentials by sensitive detection of intrinsic signals like tiny movements is an emerging neuroscience technique. We have studied various algorithms of signal processing that can enhance detection of these signals.
