Diamond for quantum communications, spintronics and quantum computing

Full text: Optically emitting defect centres in diamond display a range of unique quantum properties that offer exciting possibilities for the construction of quantum devices which employ optical read-out In this talk I will review these remarkable properties and explain why diamond is an ideal material for use in the fabrication of (i) single photon sources for quantum communications, (i i) optical fibre-based single spin read out systems and (iii) platforms for the investigation of quantum entanglement in solid state systems. The toolkit of available fabrication strategies will be presented Our most recent results on the fabrication of fibre based single photon sources and all-diamond waveguides and cavities will be reviewed.
