Mesoscopic quantum reality in the light of new technologies. Evidence for the Schrodinger cat that defies macroscopic reality has emerged for systems of several atoms, ions or photons, resulting in a Nobel award in physics in 2012.

Evidence for the Schrodinger cat that defies macroscopic reality has emerged for systems of several atoms, ions or photons, resulting in a Nobel award in physics in 2012. However, developments in quantum science technology make these states experimentally accessible at an increasingly mesoscopic level. This project will develop a theory to test mesoscopic realism, nonlocality and decoherence in experiment, focusing on cold atom and ion trap systems. This project will study multipartite nonlocality based on Bell's theorem, the Einstein-Podolsky-Rosen paradox and Schrodinger's quantum steering. As well as having fundamental significance, these demonstrations are potentially useful for metrology, secure quantum cryptography and ultra-sensitive detectors.Read moreRead less

Summary
Quantum computation and relativistic quantum information. Quantum information theory has profound implications both for practical computing and for our fundamental understanding of the universe. This project will determine the viability of one particular quantum computing platform and also develop theoretical and experimental tools to probe the interface between quantum theory and relativity.
Finding the lost particle: Majorana fermions in ultracold atoms. Majorana fermions – particles that are their own antiparticles – play a key role in future quantum technologies such as fault-tolerant quantum computers. Being considered only as a mathematical possibility over the past 75 years, they might be surprisingly materialised owing to recent rapid experimental advances. In collaboration with the world-leading cold-atom laboratories in Australia, China and the USA, this project aims to pav ....Finding the lost particle: Majorana fermions in ultracold atoms.

Being considered only as a mathematical possibility over the past 75 years, they might be surprisingly materialised owing to recent rapid experimental advances. In collaboration with the world-leading cold-atom laboratories in Australia, China and the USA, this project aims to pave a new direction to create and manipulate Majorana fermions towards realistic atomtronics devices, by using the highly controllable setting of ultracold atomic Fermi gases. This research complements the search of Majorana fermions in solid-state devices.Read moreRead less

This project aims to understand one-dimensional materials by engineering quantum wires of interacting fermions with ultracold atoms. Particles confined to move in one dimension behave differently than in three-dimensional matter, revealing quantum phases and exotic forms of superfluidity not seen in higher dimensions. Ultracold atoms allow the precise control of interactions and a perfectly isolated and defect free environment to study such phenomena not easily achieved in solid-state systems. The goal of this project is to provide quantitative insights into the thermodynamic and superfluid properties of one-dimensional quantum materials with potential significance for new innovations and applications in emerging quantum technologies.Read moreRead less

They are at the origin of many sophisticated states of matter including quantum Hall materials, topological insulators and supersolids that have potential applications in future technologies. This project aims to explore these exotic quantum states emerging in ultracold atomic gases with artificially engineered gauge fields. Unlike the solid-state systems, in which all details of the material structure are not controlled or even not known with certainty, the unprecedented controllability of the ultracold system provides a unique opportunity to gain key insights on the physics related to the gauge fields, and to advance the studies in both fundamental physics and applications.Read moreRead less
New generation periodic lattices for ultracold quantum gases. Periodic arrays of ultracold atoms trapped by magnetic microstructures will be used to mimic condensed matter systems with nontrivial geometries such as honeycomb lattices. These magnetic lattices will enable us to study exotic quantum states, such as those found in graphene, which has great potential for new-generation atomic-scale electronics.
