Summary
Development and application of super-sensitive spinning quantum sensors. This project aims to use physical rotation of diamonds on timescales faster than quantum decoherence to set new detection limits for precision quantum sensing of electric and magnetic fields. This potentially allows us to see for the first time how the Coriolis force acts on current flowing in a frame rotating 700,000,000 times faster than the earth. The project's expected outcomes are electro-magnetic sensors with unpreced ....Development and application of super-sensitive spinning quantum sensors. This project aims to use physical rotation of diamonds on timescales faster than quantum decoherence to set new detection limits for precision quantum sensing of electric and magnetic fields. This potentially allows us to see for the first time how the Coriolis force acts on current flowing in a frame rotating 700,000,000 times faster than the earth. The project's expected outcomes are electro-magnetic sensors with unprecedented sensitivity that could find application in areas ranging from detecting household wiring to locating magnetic anomalies for defence. These outcomes should fill a blind spot of quantum magnetometry, have commercial impact and expand our knowledge of quantum physics in the rotating frame.Read moreRead less

This project aims to harness the ability to control the fundamental interactions which limit the precision of a diamond quantum sensor, enabling more sensitive magnetometry. Quantum sensors are unveiling new insights into nano-scale phenomena. Single atom defects in diamonds have been at the forefront of this revolution in nano-scale sensor technology. A unique capability, spinning diamond quantum sensors at up to 500,000 rpm, fast enough that quantum properties of the defects are preserved during a cycle has been established. This project will address the long-standing problem of nano-scale solid-materials characterisation using rotationally-enhanced quantum magnetic resonance spectroscopy.Read moreRead less
Emergent many-body phenomena in engineered quantum optical systems. In recent years, scientists have realised unprecedented control over light-matter interaction. Single particle dynamics in engineered systems are now well understood, but when scaled up, the many-body behaviour remains unexplored.

These phenomena are qualitatively new behaviour ....Emergent many-body phenomena in engineered quantum optical systems. In recent years, scientists have realised unprecedented control over light-matter interaction. Single particle dynamics in engineered systems are now well understood, but when scaled up, the many-body behaviour remains unexplored. This project will significantly advance our understanding of new emergent quantum phenomena arising from engineered interactions between many particles. These phenomena are qualitatively new behaviour that cannot be explained as an extension of single-particle behaviour. The chief aim is to unravel the quantum dynamics of these systems. The project is expected to assist in producing new quantum technologies such as sources and detectors of quantum light and new atomic clocks.

This project aims to integrate quantum hyperpolarisation technology into state-of-the-art nuclear magnetic resonance (NMR) systems, potentially boosting the signal by several orders of magnitude. Understanding the structure and function of membrane bound peptides and proteins in cells in their native environments is critical in drug development.

This project aims to develop the science and tools behind device-independent quantum security for information networks. These gold-standard protocols rely on genuine quantum nonlocality but, to date, the strict performance requirements have been unachievable for general practical cases. Further, the theory of nonlocality in multiparty networks is almost completely undeveloped. The project’s anticipated outcomes are novel experiment and theory to bypass barriers and open up nonlocal network protocols. It is also expected to rigorously establish that a single-photon wavefunction after a beamsplitter is truly nonlocal. Likely future benefits include secure random numbers, secure distributed information technology and world-best photon sources.Read moreRead less
