Doped diamonds are central to a growing range of quantum-sensing technologies for future industries, including medical and defence. These diamonds must be doped with both an electron donors and active 'quantum-defects' to operate. Within existing devices, the electronic donors also create parasitic magnetic noise, due to their magnetic-spin properties. In this project we aim to investigate the growth of diamond with new electronic donors, aiming for spin-free and thus noise-free dopant properties. This should provide significant benefits to defence capability, through enhanced magnetic anomaly detection in naval environments, and health outcomes, through neural sensing of brain signals at room temperature.

掺杂金刚石是未来行业（包括医疗和国防）越来越多的量子传感技术的核心。这些金刚石必须掺杂电子供体和活性“量子缺陷”才能工作。在现有的器件中，电子供体也会由于其磁自旋特性而产生寄生磁噪声。在这个项目中，我们的目标是研究新的电子供体的金刚石的生长，旨在无自旋，从而无噪声掺杂剂的属性。这将通过增强海军环境中的磁异常探测，为防御能力提供重大益处，并通过在室温下对大脑信号的神经感知，为健康结果提供重大益处。
