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

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.

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.

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

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
Memory and light for integrated quantum systems. Optical quantum information technologies have the potential to change the way we work and play, but there are problems to be overcome: we lack both a memory for quantum information and reliable light sources that can be integrated into quantum networks. This project addresses both these issues and will bring quantum technologies closer to market.
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

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
