Optomechanical Spin-Photon Interface in Wide-Bandgap Materials
… quantum network is the lack of an efficient interface between 'stationary' quantum memories and 'flying' photonic qubits at telecommunication wavelengths. Hybrid mechanical systems aim to overcome this challenge by harnessing the ability of mechanical motion to control and couple disparate …

The tin-vacancy centre in diamond: a coherent spin-photon interface for quantum network nodes
Quantum networks require spin-photon interfaces capable of generating entanglement between a stationary qubit and flying photons. So far, such an interface with a large emission rate of indistinguishable photons and excellent spin properties has been missing. Group IV colour centres in diamond …

Visible Emitters in Hexagonal Boron Nitride as an Optically Addressable Spin Qubit Platform
Optically active spins in solid-state systems serve as excellent spin-photon interfaces, a crucial building block for quantum technologies such as information networks and sensing. This thesis presents a new spin qubit platform: visible emitters embedded in epitaxially grown hexagonal boron nitride …
