Our theme

With applications ranging from high-resolution sensing to quantum information science, spin control at the nanoscale is emerging as an area of newfound importance. Specific topics of interest guiding our research effort are (i) the development of new spin-based platforms for nanometer-resolution MRI and various nanoscale sensing protocols, (ii) quantum control of individual spin clusters for quantum information processing, and (iii) the generation of electron or nuclear spin hyper-polarization. We are presently inviting applications for a POSTDOCTORAL POSITION in our group. To learn more please click here.

To guide you through our website we have assembled a set of short movies describing some conceptual and practical aspects of our work. An intro video clip by Prof. Meriles follows below.

We are conducting a range of experiments centered on the understanding and manipulation of individual or small ensembles of paramagnetic defects. Illustrative examples along with more images and video clips can be found in our Research page. We also suggest you check out these recent Publications:
