Atomic Physics Seminar, Ashok Ajoy, MIT, “Quantum assisted metrology with Nitrogen Vacancy centers in diamond”

Thu, Jan 7, 2016, 2:00 pm to 3:30 pm

In the past few years, the development of novel quantum sensors based on the Nitrogen Vacancy (NV) center in diamond has shown tremendous promise for high sensitivity metrology at small length scales. In this talk, I will outline our efforts to use these sensors for high resolution nanoscale Magnetic Resonance Imaging (MRI) [1-3], specifically with the aim of obtaining structural information of single molecules at room temperature. I will also detail how an ensemble of NV centers could be constructed into a sensitive and stable sensor of rotations (NV gyroscope [4]), and discuss efforts underway in our lab towards building a prototype.
