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. However, studying these biomolecules by conventional NMR under ambient conditions is challenging due to sensitivity limitations. The technology developed by this project will be a significant step forward in NMR and the new science enabled may have far reaching consequences for the study of peptides and proteins of live cells for the development of new drugs and anti-biotics, with direct societal benefits and flow-on economic benefits.Read moreRead less

Density modulations and superconductivity in two-dimensional quantum gases. The project aims to investigate the interplay between pairing (superfluidity) and pattern formation (eg stripes) in quasi-two-dimensional quantum systems. The close proximity of these phases is a recurring theme in layered materials which could hold the key to understanding phenomena such as high temperature superconductivity.

The project aims to investigate the interplay between pairing (superfluidity) and pattern formation (eg stripes) in quasi-two-dimensional quantum systems. The close proximity of these phases is a recurring theme in layered materials which could hold the key to understanding phenomena such as high temperature superconductivity. The project plans to investigate these phases in dipolar gases, which provide a clean, controlled environment for novel many-body phenomena. Within this setting, it plans to test established theories of pairing and develop accurate descriptions of density modulations, thus providing fundamental insights into strongly correlated systems. The new states of matter discovered in the project could form the basis for new quantum devices; in particular, a deeper understanding of stripe phases may allow us to use them for data storage.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 investigate the effects of a fundamental minimum length on the nature of gravity and on how accurately we can make measurements in our world. The key challenge is to combine our best theories of fundamental physics to model what happens at ultra-short distances. This project will generate new knowledge at this interface by using a novel approach inspired by information theory. The expected outcomes are new connections between fundamental limitations on measurements, the nature of gravitation, and ultra-small-scale quantum physics. The benefit of this work is breaking the logjam in answering the most important open question in all of physics: how to unite quantum theory and gravitation.Read moreRead less

This project aims to create a new exotic form of quantum matter in which a many-body system of ultracold atoms bouncing on a vibrating mirror spontaneously self-organises its motion with a period tens of times longer than the driving period of the mirror. Such ‘time crystals’ are predicted to be robust against external perturbations and to persist for very long times. The project expects to generate new knowledge on exotic non-equilibrium crystalline phenomena in the time domain, such as many-body localisation with temporal disorder, which has counter-intuitive characteristics such as absence of thermalisation and vanishing direct current transport. Time crystals could provide significant benefits for the storage and transfer of quantum information, and this, and other outcomes may ultimately lead to commercial products.Read moreRead less
