This project aims to identify new strategies to reduce decoherence in quantum computer components using an interdisciplinary approach based on quantum physics, materials science, and engineering. This project involves investigating the effect of

This project aims to establish equipment for advanced surface analysis to provide Australian researchers with cutting-edge capabilities in surface science. Vital chemical and physical reactions often occur at surfaces. Understanding these reactions requires analysis of the composition and electronic structure of the surface and near-surface regions. Neutral impact collision ion scattering spectroscopy and inverse photoemission spectroscopy measure concentration depth profiles and electronic structure. The depth resolution of the profiles is in the order of the distance between two neighbouring atoms in a solid or liquid and is the best currently achievable. The equipment providing these capabilities is expected to support research with applications in photovoltaics, catalysis, colloid surfaces and interfaces, coatings and nanocomposites.Read moreRead less
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.

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

This project aims to develop a prototype electric field induced second harmonic generation metrology setup for studying thin film dielectric interfaces on silicon in partnership with Femtometrix. The quality of these silicon-dielectric interfaces, which are affected by trapped charges and defects, are critical for microelectronic and optoelectronic device manufacturing. Through several proposed methodologies to separate the effect of interface and bulk signals, it is expected that the sensitivity of the prototype setup will exceed the previous record of 1 kV/cm. This metrology technique will be further expanded for applicability to silicon photovoltaics, specifically passivating contacts which cannot be studied via conventional techniques.Read moreRead less
