Synthesis of enriched silicon for long-lived donor quantum states. 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 deple ....Synthesis of enriched silicon for long-lived donor quantum states. 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

Re-engineering the diamond lattice. This project aims to engineer electrical and magnetic structures in diamond that can be measured at the nanoscale by ultra-sensitive magnetometers formed in-situ by nitrogen-vacancy colour centres. By careful control of ion implanted acceptor atoms the project will examine the transition of the diamond lattice from semiconducting, to magnetic, to superconducting phases predicted to exist from advanced theory. It is expected that the project outcomes will open ....Re-engineering the diamond lattice. This project aims to engineer electrical and magnetic structures in diamond that can be measured at the nanoscale by ultra-sensitive magnetometers formed in-situ by nitrogen-vacancy colour centres. By careful control of ion implanted acceptor atoms the project will examine the transition of the diamond lattice from semiconducting, to magnetic, to superconducting phases predicted to exist from advanced theory. It is expected that the project outcomes will open the way to monolithic integration of diamond based quantum devices that exploit the remarkable attributes of the diamond lattice and the long-lived nitrogen-vacancy quantum bit subject to intensive study worldwide.Read moreRead less
