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

Multi-colour ultrashort soft X-ray pulses. This project aims to create multi-colour, ultrashort, highly coherent, bright pulses of soft X-rays based on high-harmonic generation in a table-top multiple-section gas cell.

This project aims to create multi-colour, ultrashort, highly coherent, bright pulses of soft X-rays based on high-harmonic generation in a table-top multiple-section gas cell. Studying multi-electronic and non-adiabatic processes and other fundamental aspects such as multi-electronic correlations and non-Born-Oppenheimer vibronic couplings in complex molecules is a major challenge in current ultrafast photochemistry research. This project will use multiple driving pulses with different carrier frequencies to control the spectral properties and time delay of the pulses. It will use the soft X-ray source to develop an ideal platform for studying multi-electronic and non-adiabatic processes, multi-electronic correlations and non-Born-Oppenheimer vibronic couplings in complex molecules. This is expected to advance materials science, paving the way to soft X-ray technologies.Read moreRead less

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
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.

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

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. However, non-local quantum correlations are critical for quantum devices to surpass classical systems.

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
