From atomic-scale imaging to quantum fault-tolerance with spins in diamond

Owing to its exceptional spin properties and bright spin-photon interface, the nitrogenvacancy (NV) center in diamond has emerged as a promising platformfor quantum science and technology, including quantum communication, quantum computation and quantum sensing. In this thesis we develop novel methods for atomic-scale imaging and high-fidelity control of complex nuclear-spin systems coupled to the electron spin of an NV center in diamond. This well-controlled quantum system provides new opportunities in quantum sensing, quantum information processing, and may also form the building block of a large-scale quantum network, one of the key goals in quantum technology.
