The tin-vacancy centre in diamond: a coherent spin-photon interface for quantum network nodes
… tin-vacancy centre in diamond has both excellent optical properties and long spin coherence times at elevated cryogenic temperatures. High-fidelity quantum control, however, has remained elusive. In this thesis, we introduce a new platform: deterministically strained tin-vacancy centres in a thin …

Non-Hermitian Whispering Gallery Mode Optical Microresonators and Their Applications
<p>Whispering-gallery-mode (WGM) optical microresonators, in which light propagates along the circular rims due to the total internal reflection, have attracted broad attention in the past two decades. Owing to the ultrahigh quality factor and the small mode volume, WGM resonators can significantly …
