Abstract :

Nitrogen-Vacancy (NV) centers in diamond have interesting properties for a number of quantum technologies including quantum information processing and nano-scale Nuclear Magnetic Resonance (NMR). In this presentation, I will talk about our recent experimental research on NV centers for the applications of quantum information processing and hyperpolarization of nuclear spins. I will first introduce NV centers, their interesting properties and some of their applications. Then, I will talk about interactions between single electron spins of NV centers and proximal nuclear spins and interesting level anti-crossings that occur because of these interactions. Some of the interesting results of this analysis are (i) dynamics of a single-spin driven beyond the rotating-wave approximation and (ii) Decoherence-free subspaces. Next, I will talk about transferring polarization of optically pumped NV centers to bulk 13C nuclear spins of the diamond lattice. Finally, I will discuss strategies to realize scalable quantum information processing using NV centers and transferring polarization of optically pumped NV centers to nuclear spins outside the diamond surface.
