The aim of this theoretical physics project is to develop ultra-precise sensing capabilities for two main applications: ultrastable inertial sensors for improved navigation and gravimetry, and to search for signatures of quantum gravity. This project expects to improve the performance of quantum sensors via the use of machine optimisation, and may lead to much-needed experimental data to help guide one of the most challenging problems in theoretical physics: the quantisation of gravity. The expected outcomes of this project are enhanced quantum sensor design, leading to improved inertial sensing technology. This should provide benefits such as improved capabilities for minerals exploration and monitoring the movement of ground water.Read moreRead less

Spinning spins: measuring geometric phases in rotating quantum systems. 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 rota ....Spinning spins: measuring geometric phases in rotating quantum systems. 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

Designer defects in diamond for solid state quantum networks. This project aims to develop an artificial atom in diamond that can connect to other nodes in a network. Network connectivity and data distribution are increasingly important in today's information economy.

This project aims to develop an artificial atom in diamond that can connect to other nodes in a network. Network connectivity and data distribution are increasingly important in today's information economy. Tiny glowing artificial atoms in coloured diamonds can receive, store and send information in a network using laser light and microwaves. Because they work at the level of individual atoms and photons, they can use quantum-weirdness to achieve feats impossible even for supercomputers on the classical internet. The proposed device is expected to make it easier to construct technologies that move beyond the limitations of existing infrastructure thus satisfying the unmet core requirements for a quantum network.Read moreRead less

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
Quantum networks based on superconducting circuits and dissipative channels. Superconducting circuits have great potential for probing and using quantum nature on a chip but lack networking capabilities between remote sites.

Superconducting circuits have great potential for probing and using quantum nature on a chip but lack networking capabilities between remote sites. However, non-local quantum correlations are critical for quantum devices to surpass classical systems. This project aims to create capabilities for establishing entanglement between remote superconducting chips using non-local dissipative interaction. Within this approach the created entanglement can be also preserved as long as necessary as a resource for quantum protocols. The resulting technology is expected to enable quantum information processing in superconducting circuits on fundamentally larger scales and provides a powerful platform to test the limits for building artificial quantum systems.Read moreRead less

Calming the Superfluid Storm: Taming Turbulence in Superfluid Devices. Turbulence, the chaotic flow of fluids, occurs in the vast majority of fluid flows in nature. This project aims to develop a new understanding of turbulence in superfluids, a class of quantum fluids which can flow without friction.

This project aims to develop a new understanding of turbulence in superfluids, a class of quantum fluids which can flow without friction. The significance is that aspects of turbulence are universal, so that discoveries in superfluid turbulence will provide fundamental insights into all forms of turbulence. The expected outcomes are solutions to two outstanding questions – what are the universal laws of turbulent flow for superfluids, and what new forms of quantum vortex matter are possible? New insights into turbulence will benefit all applications which rely on its understanding, for example in medicine, aviation, and climate modelling.Read moreRead less
