Diamond has shown itself to be a leading material for a range of applications requiring quantum-state control such as quantum computing and sensing. This is by virtue of the fact that the quantum-state (a ‘on’ or ‘off’) of engineered impurities (‘qubits’) contained within diamond can be controlled and read-out simply by shining light on the diamond, combined with the application of a microwave field, and measuring light that is emitted. Unlike many other materials such techniques can be conducted at normal room temperatures, instead of requiring dramatic cooling to temperatures < -173 degrees C. These ‘quantum defects’ can be used to sense very small magnetic fields, hence sensors made from diamond have the potential to be used in applications for mining, underwater pipe detection and as diagnostic tools in medicine. Critical to the development of these devices is to have a man-made diamond material with an optimised fraction of quantum defects that is both reproducible and can be manufactured at scale. Therefore this project will work on all the elements required to turn prototype magnetic-field sensors into a productionised commercial process to enable the next generation of devices.

金刚石已被证明是一系列需要量子状态控制的应用的领先材料，如量子计算和传感。这是因为钻石中含有的工程杂质（“量子位”）的量子状态（“开”或“关”）可以简单地通过在钻石上照射光来控制和读出，结合微波场的应用，并测量发射的光。与许多其他材料不同，这种技术可以在正常的室温下进行，而不需要急剧冷却到< -173摄氏度的温度。这些“量子缺陷”可用于检测非常小的磁场，因此由金刚石制成的传感器有可能用于采矿，水下管道检测和医学诊断工具。开发这些设备的关键是拥有一种具有优化的量子缺陷分数的人造金刚石材料，该材料既可再现又可大规模制造。因此，该项目将致力于将原型磁场传感器转化为生产化商业过程所需的所有元素，以实现下一代设备。
