Deterministic spin and photon control with a symmetry protected colour centre
… this thesis, the negatively charged tin vacancy centre (SnV) in diamond is presented as a viable, symmetry protected, platform for quantum networking applications. The stationary qubit in the network is formed by the SnV centre's intrinsic optically addressable spin-1/2 qubit. This thesis …

Group-IV Colour Centres in Diamond for Multi-Photon Entangled State Generation
Colour centres in diamond have, in recent years, been heralded as a promising platform for realising quantum communication and computing. In particular, attention has been given to generating entanglement between colour centres to enable quantum networking and the generation of highly entangled …

A nanophotonic platform for the tin-vacancy centre
… efforts to establish new scalable architectures, colour centres in wide-bandgap semiconductors are particularly attractive, as they could leverage well-established semiconductor manufacturing processes on the route towards commercial technologies. In this thesis, we study the tin-vacancy centre in …

Effects of Low Temperature and Structure on the Photophysics of Alkylammonium Lead Halide Semiconductors
… at low temperatures due to a Frenkel defect (f-centre). Additionally, we see evidence of biexciton emission in dodecylammonium lead iodide films at high excitation densities below temperatures of 225 K. The films in this study were seen to adopt two coexistent phases of dodecylammonium lead …

Three Grains, Two Photons and a Colourful Diamond
… of optical studies on the Silicon-Vacancy (SiV) colour-centre in diamond are reported. Coherent Population Trapping (CPT) experiments performed using electrically actuated diamond micro-cantilevers show that the ground state splitting, and therefore the strength of the electron-photon coupling …

The silicon-vacancy centre in diamond for quantum information processing
… solids, the negatively charged silicon-vacancy centre in diamond (SiV$^{−}$) has attracted attention for its very promising optical properties for such a network. In this thesis, we investigate the spin properties of the silicon-vacancy centre as a potential spin-photon interface. First, we use …
