Quantum control of optically active defects in the solid state
… the electronic spin of the same defect was optically initialized and read out. Remarkably, both of these achievements occurred under ambient conditions. In the decades that have followed, the study of optically active defects in the solid state have garnered significant interest for quantum …

NV diamond project for nEDM
… sensors for measuring both, electric and magnetic fields at room temperature and also at 4 K. This thesis discusses different techniques used to probe the NV centers electronic structure. The first, Optically Detected Magnetic Resonance (ODMR) allows us to probe the Zeeman and Stark …

Measurement and control of exciton spin in organic light emitting devices
… molecule, and another that is a polymer. Second, optically-detected magnetic resonance effects in organic semiconductors are shown to be unrelated to exciton formation processes, contrary to the current understanding. A quenching-based model is developed and shown to completely describe the data. …

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 …

The silicon-vacancy centre in diamond for quantum information processing
… excitation of an SiV$^{−}$ centre in an external magnetic field to selectively address different electronic states and analyse the resulting fluorescence. We find evidence of selection rules in the optical transitions revealing that the centre possesses an electronic spin S = 1/2. Making use of …

Optics-Based Quantum Information and Sensing Platforms Utilizing the Nitrogen-Vacancy Center in Diamond
… the spin population of the defects allow for optically detected magnetic resonance (ODMR), with the resonant frequency depending on the local magnetic field. Two-dimensional images of the magnetic field at the surface of the diamond are thus obtained, with a magnetic field sensitivity of 2.4 …

Opportunities for multimodal quantum sensing in intracellular environments
… of sensing modalities, from temperature, magnetic field and electric field which can be sensed directly by the NV to pH which can be targeted with the aid of surface functionalisation. While these modalities have so far been demonstrated individually, the ability to simultaneously sense …
