Improving the coherence properties of a quantum sensor
Our quantum sensor of choice, the nitrogen-vacancy center in diamond, is on its way to become the world's smallest MRI scanner. It could give a 3D image of a single bio molecule while simultaneously resolving the chemical components. One limiting problem on this way is the reliable preparation of nitrogen-vacancy centers with long coherence times. We provide a state-of-the art measurement setup and a handful of ideas how to approach this task. We are looking for an enthusiastic student to try several preparation approaches and to perform quantum measurements on the coherence properties of the resulting single quantum sensors. Favorable personality qualities: interest in quantum information science, fun with handicrafts and no fear of software (python)

Nuclear Magnetic Resonance Microscopy

Nuclear Magnetic Resonance Microscopy

Magnetic resonance imaging (NMR/MRI), is one of the most powerful techniques to record three-dimensional images of nearly arbitrary samples. Current devices, such as those found in hospitals, cannot record details smaller than 1mm.  

Our group aims to push MRI to a microscopy technique by improving its spatial resolution down to the sub-nm range, the scale of single atoms. This ambitious goal has recently become a realistic prospect by a new generation of quantum sensors for magnetic fields. They are based on the nitrogen-vacancy (NV) color defect in diamond and could detect fields as small as the NMR signal of a single molecule [1,2].

We are looking for a MSc student to develop the next generation of our chip-scale NMR spectrometers, and to perform experiments on magnetic resonance imaging with a spatial resolution in the nanoscale range. 

Techniques:

* You will learn to fabricate microscale electromagnets in one of our clean rooms, and optimize our fabrication techniques for your project and others. 

* You will design a sensor chip for microscale NMR detection and upgrade software and optics of one of our setups to perform the experiment. 

* You will design, implement and analyze quantum control protocols to record nanoscale MRI images.
