Fabrication strategies for diamond-based quantum devices: concepts to applications
Grant number: DP1096288 | Funding period: 2010 - 2015
Twenty first technology must respond to the imperatives of low-power, high speed, and integrated functionality. The application of our most advanced scientific understanding is required to meet these imperatives: quantum physics. Quantum information Science is radically altering our understanding of physics, and is ripe to change engineering and technology. One of the most promising material platforms for exploiting quantum effects is diamond, and our project seeks to transition diamond from its role as scientific testbed, to the material of choice for quantum technologies
