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.Read moreRead less

We have discovered a method to make silicon highly enriched in the desirable spin-zero isotope using readily available ion implantation tools. This “semiconductor vacuum” is essential for building future quantum computer devices using the quantum spin of millions of implanted atoms with revolutionary capabilities. We have demonstrated long-lived implanted donor atom quantum states in prototype material, made possible by the depletion of background spins in natural silicon and now aim to push the enrichment to greater extremes. We will integrate the extreme material into functional devices that use electrically detected electron spin resonance to probe exceptionally durable quantum states and open a near-term pathway to large-scale devices.Read moreRead less
