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

This project aims to develop new detection and control techniques to study interacting many-body quantum systems in an ion trap. The understanding of quantum correlations is essential for many of the future applications in quantum technology, such as quantum scale materials, quantum sensing and quantum computation. In particular, understanding quantum magnetism is on the forefront of modern physics. The project is expected to advance the extraction of time-domain information about the generation and spread of quantum correlations. This project should provide significant benefits in the understanding of exotic condensed matter phenomena such as high-temperature superconductivity or spin liquids. The knowledge and techniques developed in this project will also be valuable for other research areas from material science and atomic physics to quantum science.Read moreRead less
