Thesis Defense Announcement: Cyrus Zeledon

Optically active spin defects in the solid-state are key for applications in quantum information science, quantum sensing, and quantum networks. In particular, the neutral divacancy (VV0) defect in silicon carbide can be leveraged for these applications because it boasts long coherence times, a robust spin-photon interface, and the added benefit of being hosted in a technologically mature semiconductor. Additionally, nuclear spins inherent in the material provide a key resource for local quantum memories due to their long coherence times. In this thesis, we demonstrate that in isotopically purified material, VV0 qubits display record-long coherence times of individual electron and nuclear spins, single shot readout of the electron and nuclear spin states, and in-situ device tunability of the electron’s optical and spin properties. Ultimately, these findings harness the synergy between materials growth and device integration to create a highly coherent solid-state quantum node.
