en.Wedoany.com Reported - The Commonwealth Scientific and Industrial Research Organisation (CSIRO) is collaborating with the University of Melbourne and Japan's National Institutes for Quantum Science and Technology (QST) to transform inexpensive industrial-grade diamond particles into precision nanodiamonds suitable for quantum sensing technologies.

The project aims to establish a scalable and lower-cost manufacturing pathway for quantum-grade diamond materials. These materials can be produced domestically in Australia to reduce reliance on international supply chains and support the country's broader quantum technology development plans.

Specially engineered diamonds can function as highly sensitive quantum sensors to detect weak magnetic signals generated by nearby molecules. This capability can be applied in chemical analysis, environmental monitoring, medical diagnostics, defense systems, and future quantum computing technologies.

The sensing function relies on atomic-scale defects in the diamond crystal structure—nitrogen-vacancy (NV) centers. These defects enable diamonds to respond to changes in magnetic fields, electric fields, temperature, and other environmental conditions, allowing them to operate as nanoscale sensors.

Researchers are focusing on developing methods to create stable and effective NV centers near the surface of nanodiamonds. This location is critical for achieving optimal sensing performance. The process involves creating vacancies in the diamond lattice and combining them with nitrogen atoms to form sensing centers.

This technology is expected to promote cleaner and safer chemical manufacturing by improving the detection and identification of chemicals in complex mixtures. Future potential applications also include detecting disease biomarkers and trace environmental pollutants.

Many existing diamond-based quantum systems rely on scarce and expensive single-crystal diamond materials. By developing a scalable route for nanodiamonds with sensing-ready NV centers, researchers aim to reduce production costs and expand the application scope of quantum sensing technologies.

The collaboration with QST provides the research team access to specialized quantum beams and irradiation facilities not currently available in Australia. This partnership aims to cultivate local expertise and ultimately establish domestic production capabilities for quantum-grade diamond materials, reducing dependence on large overseas facilities.

The project is funded by the Australian Government's Global Science and Technology Diplomacy Fund and is part of broader Australia-Japan scientific cooperation.

In the next phase of the project, researchers will focus on improving the consistency and performance of nanodiamonds, including optimizing the positioning of NV centers and refining surface treatments to enhance sensing stability. These materials will also undergo further testing and validation in practical sensing applications.

The long-term goal is to establish end-to-end Australian manufacturing capabilities for quantum-grade diamond materials, supporting local industry participation in the emerging global quantum technology supply chain.
