About Our Research

Our group’s research focuses on understanding and controlling solid-state spins at the nanoscale. We are interested in their interactions with their environment and electromagnetic radiation from the microwave to the optical domain. These interactions may find applications in magnetic technology and devices as well as in the emerging area of quantum information science and technology.

Our primary interests include:

  • Using heat and light to measure magnetization dynamics with high spatial and temporal resolution
  • Quantum control over solid-state spins, with an eye toward quantum enhanced technology
  • Understanding the photo- and spin-physics of point defects in wide-bandgap semiconductor materials
  • Micro- and nano-fabrication of photonic and magnetic structures aimed at probing spin at the nanoscale

The outcome coherent storage of various quantum states prepared in a single nitrogen vacancy center electronic spin, stored in a single nitrogen nuclear spin for a time τ, and then transferred back to the electronic spin for measurement. These measurements show a fidelity of 88±6% for quantum storage over 10 μs.

Our research group is based in the School of Applied & Engineering Physics at Cornell University, but we also have ties with the Cornell Center for Materials Research and the Cornell Nanoscale Science and Technology Facility
