Quantum Sensing with Nitrogen Vacancy Centers in Diamond
Seminar Hall 31, 2nd Floor, Main Building
Abstract:
Color centers in diamond have proven to be promising candidates for not only quantum computing but also for quantum sensing. Amongst the various color defects, nitrogen-vacancy centers (NV centers) could provide a platform for precision magnetometry allowing for nanoscale magnetic imaging with applications in brain imaging, magnetotatic bacteria, quantum materials, geomagnetic fields, and many others. In this talk I will give an overview of our research towards a variety of applications of NV centers for quantum sensing. I will describe our work towards dynamic widefield imaging, its challenges, and its application to reconstructing current flows in semiconductor chips and magnetic materials with bulk NV centers. Further, I will discuss the use of nanodiamonds for magnetic field and temperature sensing.
