Magnetometry

The nitrogen defect (NV) center is a promising quantum system with wide applications. In addition to quantum information technology, it is particularly used as a quantum magnetic sensor [1, 2, 3]. Although previous research has demonstrated the high potential of an NV-based sensor, complete sensor systems have rarely been practically realized.

In one project, we are developing such a measurement system towards application, e.g. in biomedicine. To this end, we are investigating technologies with which the components of the diamond magnetometer can be integrated into a compact and practical device.
