Condensed Matter/Materials & Biological Physics Seminar with Tongcang Li on Spin Qubits in 2D Materials

Spin defects in solids such as diamond have been widely used for quantum sensing and quantum network applications. The recent discovery of spin qubits in hexagonal boron nitride (hBN), a van der Waals layered material, provides new opportunities. Thanks to its layered structure, hBN can be easily exfoliated and integrated with other materials and nanostructures. For example, spin qubits in hBN will be particularly suitable for studying 2D magnetic materials. This talk will briefly review recent developments with spin defects in 2D materials. I will also report our recent work on femtosecond laser writing of spin defects in hBN and plasmon-enhanced high-contrast hBN spin defects for quantum sensing.
