The quantum geometric phase has long been viewed as an interesting, but somewhat mysterious, feature of quantum mechanics. However, the ability to harness and control geometric phase in individual quantum systems may drive the development of a new class of quantum technologies. This project aims to measure, for the first time, geometric phase due to the macroscopic motion of an atom-scale quantum system, specifically in rotating nitrogen-vacancy defects in diamond. It is expected that these proof-of-principle measurements will provide the basis for the future development and design of new nano-scale quantum gyroscopes and set the foundations for using nano-diamonds as rotational diagnostic tools in a range of important nanoscopic systems.Read moreRead less

Knowledge, Ignorance, and Security in Higher-dimensional Quantum Systems. This project aims to provide new understanding of information and security in higher-dimensional systems, and to exploit this to deliver a secure, high-capacity, quantum image transfer protocol for quantum communication and quantum cryptography technologies.

This project aims to provide new understanding of information and security in higher-dimensional systems, and to exploit this to deliver a secure, high-capacity, quantum image transfer protocol for quantum communication and quantum cryptography technologies. In quantum physics, the best possible knowledge of a whole does not include the best possible knowledge of the parts: not knowing any of the letters of a word does not imply not knowing what the word is. This project aims to examine the high-dimensional transverse spatial modes of photon to show that the converse is also true: not knowing the word does not imply not knowing any of the letters. Project outcomes may have applications in remote sensing and surveillance.Read moreRead less

This project aims to experimentally demonstrate a device needed to bus quantum information between defect clusters in large scale quantum computers. Quantum computers could transcend limits of today’s ‘classical’ computers. Diamond is a proven platform for small-scale quantum computing and simple quantum algorithms have already been demonstrated using small clusters of diamond defects. To build a large-scale quantum computer that can realise the potential of quantum computing, a device must be invented to bus quantum information between defect clusters. This project will experimentally demonstrate physical mechanisms that were theoretically identified for the operation of such a device. This is expected to make a quantum bus for large-scale diamond quantum computers possible.Read moreRead less

This project aims to extend the density and coherence of qubits stored in superconducting-based quantum processors, by exploring the concept of hybrid quantum systems. Quantum computers are expected to impact a diverse range of sectors, from medicine to national security. This project seeks to develop an enabling technology, a memory, for scaling a quantum computer constructed from superconducting circuits, such as those being developed in commercial laboratories. Such scaling would improve the capacity of these processors to tackle complex problems.

Quantum technologies could transcend the limits of today’s current technologies. Defects in diamond are a proven platform for the development of quantum microscopes which could yield images of nature at the atomic scale and quantum computers that may solve problems too difficult for classical computers. This project will employ an integrated research approach, spanning fundamental theory to device design and demonstration. Key anticipated outcomes are international collaboration and knowledge, capability and training in quantum microscopy and computing. This will benefit Australia by securing its global competiveness in the emerging market of quantum technology.Read moreRead less
