The detection of tiny magnetic fields is at the heart of many applications such as magnetic resonance imaging and data storage devices. Defect centers in diamond offer the possibility for optically detecting magnetic fields with unprecedented spatio-temporal resolution and high sensitivity under ambient conditions. Because of the compatibility of diamond with biological systems, this suggests the possibility of imaging the activity of neural networks or single magnetically tagged biological cells.
In this project, you have the opportunity to be part of a team developing novel sensing techniques with the highest sensitivities obtained under ambient conditions. You will construct and set up an experimental platform, integrating the diamond magnetic field sensor and facilitating the detection of a neural signal in a human arm. You will work with innovative diamond quantum technology, learn about optical imaging techniques, sensing at the fundamental quantum limit, and fast data processing and analysis.
Image: Under stimulation with green laser light, the diamonds fluoresce in red; this is made visible in the image by filtering away the green light. The intensity of the red fluorescence light allows us to detect a magnetic field.
