This project aims to help companies and government flagships (including Australian) to achieve quantum supremacy- to build a computer based on quantum physics so complex that it outperforms all conventional computers. There is a race to do so because quantum computers will have a huge technological, scientific and economical impact. But currently the error rate of quantum computers is still too high. The devices are immensiley complex, but the models used to drive them are far too simplistic. This project will provide accurate and innovative models in this new era of quantum complexity, thus better controls, which will be tested on cloud-based quantum computers. The expected outcomes are robust quantum computers towards quantum supremacy.Read moreRead less
Solid-state quantum communication technology. This project will develop the quantum information devices required to create a quantum communication network for the ultra-secure transmission of data.

Finding the lost particle: Majorana fermions in ultracold atoms. Majorana fermions – particles that are their own antiparticles – play a key role in future quantum technologies such as fault-tolerant quantum computers. Being considered only as a mathematical possibility over the past 75 years, they might be surprisingly materialised owing to recent rapid experimental advances. In collaboration with the world-leading cold-atom laboratories in Australia, China and the USA, this project aims to pav ....Finding the lost particle: Majorana fermions in ultracold atoms.
