The Quantum Sensing Laboratory at the Laser Centre focuses on nitrogen-vacancy (NV) centers in diamonds in the following fundamental and application-oriented research areas:
- Basic research of NV centers in diamonds.
- Development and compactization of vector magnetometers.
- Wide-field imaging of magnetic fields.
- Fabrication and characterization of NV sensors.
Scope.
Because of their robustness, simplicity, and high spatial resolution, NV centers in diamond provide possibly the most promising approach to developing practical quantum sensors. Significantly, they form the basis for the first quantum technology that has been commercialized (scanning NV microscopes) and new applications and techniques are continuously being developed. Our laboratory is on the cutting edge of this development. The laboratory has several setups for NV magnetometry, including a unique wide-field magnetic imaging microscope capable of mapping magnetic fields with optical resolution in real-time. In addition, the laboratory facilities enable fabrication and characterization of quantum sensors with ensembles of NV centers in diamond, as well as advanced pulsed magnetometry experiments. Our laboratory students gain expertise in the development and construction of compact NV magnetometers for space and navigation applications within the framework of several international projects.
International cooperation.
Our cooperation with several leading labs and experts in Europe and North America leads to joint research and publications, as well as the exchange of visiting scientists and students. Specifically, these experts are Prof. Dima Budker at Berkeley and Mainz universities, Prof. Victor Acosta at the University of New Mexico, Prof. Abdelghani Laraoui of the University of Nebraska and many others.
