Abstract: Quantum sensing is regarded as one of the cornerstones of modern quantum science and technology that are poised to drive new technological advancements of this century while enhancing our understanding of fundamental sciences. Spin, a quantum mechanical property, associated with certain point defects in solid state materials has emerged as an excellent probe for sensing physical quantities with high sensitivity. Nitrogen-vacancy (NV) point defect in diamond is a leading candidate for quantum sensing of external magnetic field with high sensitivity and unprecedented spatial resolution at ambient conditions. This talk will try to cover the NV-based magnetic field sensing schemes, current state of the art sensitivity with its limitations, and future prospects of this technology.

About the Speaker: Vinaya is currently a post-doctoral fellow at the Institute for Quantum Science and Technology, University of Calgary, Canada. His current research is broadly based on quantum nanophotonics, with a focus on enhanced quantum sensing, single-spin spectroscopy, and creating interfaces for light-matter interactions in diamond. He completed his MSc in Physics from Mangalore University and his PhD from the Max Planck Institute for Biophysical Chemistry in Germany, where he worked on diamond-based quantum sensing.
