Quantum Nanostructure Positioning for Breakthrough Quantum Photonics. The integration of quantum nanostructures in optical devices has been proposed to improve the efficiencies of existing optical devices and create new classes of quantum photonics.

The integration of quantum nanostructures in optical devices has been proposed to improve the efficiencies of existing optical devices and create new classes of quantum photonics. Limiting progress is that many nanostructures are made through bottom-up processes with inherently randomly distributions, making integration into devices problematic. Lithographic nanostructure fabrication is rarely an option as it leads to diminishes performance. Here, we propose a new and unique nanostructure positioning technique incorporated directly into the growth process. It interfaces bottom-up technologies with device fabrication, facilitating incorporation of nanostructures in photonic devices, and may be transferrable to a variety of other systems.Read moreRead less

Summary
Quantum control of sound with light. This project aims to build the first photonic architecture capable of controlling the quantum properties of acoustic waves travelling in crystalline materials and quantum fluids. This level of control is expected to herald new capabilities in sensing applications, quantum information and quantum computing. The project seeks to develop a silicon-based photonic platform that enables the preparation of non-classical states of sound within superfluid helium. This ....Quantum control of sound with light. This project aims to build the first photonic architecture capable of controlling the quantum properties of acoustic waves travelling in crystalline materials and quantum fluids. This level of control is expected to herald new capabilities in sensing applications, quantum information and quantum computing. The project seeks to develop a silicon-based photonic platform that enables the preparation of non-classical states of sound within superfluid helium. This new platform will also be used to develop an ultra-compact silicon-chip based laser. The project outcomes should provide a deeper understanding of quantum fluids and quantum mechanics, and enable the realisation of new quantum technologies with substantial commercialisation potential.Read moreRead less

Summary
Superfluid optomechanics with quantised vortices. This project aims to develop new technologies to probe and control the flow of superfluid helium at size-scales never before possible. Superfluid helium is the only quantum liquid, characterised by flow without dissipation and quantised vortices. Leveraging the techniques of cavity optomechanics, this project aims to demonstrate control of superfluid helium properties at the quantum level, including the first demonstration of laser-cooling of a l ....Superfluid optomechanics with quantised vortices. This project aims to develop new technologies to probe and control the flow of superfluid helium at size-scales never before possible. Superfluid helium is the only quantum liquid, characterised by flow without dissipation and quantised vortices. Leveraging the techniques of cavity optomechanics, this project aims to demonstrate control of superfluid helium properties at the quantum level, including the first demonstration of laser-cooling of a liquid into its quantum ground-state. The devices developed in this project will also serve as probes of unprecedented sensitivity for the study of 2D superfluid helium. The new technologies developed will have potential for broad uptake in the scientific community and generation of intellectual property and patents for quantum technology and inertial sensors.Read moreRead less
