I am an ARC DECRA Fellow in the Precision Measurement Group in the Institute for Photonics and Advanced Sensing (School of Physics Sciences), working towards realising a fibre-based optical quantum information network for absolutely secure communications and next-generation computing. I obtained my PhD in Physics from the Australian National University in 2013, where I developed techniques to store and manipulate optical quantum information. In 2013 I moved to the University of Melbourne to work on the development of a cold atom electron/ion source, our goal being to create ultra-short ultra-bright bunches of electrons for single-shot diffraction imaging of biological samples, as well as incredibly focused ion beams for sub-nanometer resolution fabrication. I was awarded a McKenzie Fellowship from the University of Melbourne from 2014-2016, which allowed me to investigate novel methods to improve the source performance.

Our aim is to combine Australia's pioneering work developing specialised atom-filled optical fibres with world-leading quantum information storage protocols to probe the extreme limits of atom-light interactions. This will enable the creation of a compact, robust and modular node to efficiently store and process packets of optical quantum information. The node will integrate directly with current communications infrastructure, allowing for the creation of a quantum internet - the vital missing ingredient needed to overcome the significant experimental hurdles that are limiting the potential of current quantum technologies. We have recently published work in Physical Review Applied showing successful loading of a record number of laser-cooled atoms into a hollow-core fibre (as shown in the movie below). This work was reported on in the Adelaide Advertiser, The Lead, and the UK Daily Mail along with other international news outlets.

Creating a Quantum Information Node: the above movie shows the silhouette of a cloud of almost a billion cold atoms, each a few millionths of a degree above absolute zero, as they are released from a magneto optical trap, fall under gravity and are optically guided into our hollow-core fibre (white silhouette).

Our work has been featured in an ABC news story about photonics research in Adelaide (full news clip here), on Scope, and I have been interviewed on Radio Adelaide's Subatomic program. For more information on the research being carried out by the Precision Measurement Group, please see our website.

I am also involved in outreach through The Amazing University of Adelaide Laser Radio program. For this work I was awarded the 2018 SA Tall Poppy of the Year award at the SA Science Excellence Awards.

Currently Held Grants and Fellowships:

  • Fulbright Future Scholarship (2019-2020)
    • Title: Changing Colours in Optical Fibres: The Key to Long-Distance Quantum-Secured Communications
    • Chief Investigators: B. M. Sparkes
    • Funding: $13,000
    • Summary: Information encoded onto single particles of light is the key to future global cybersecurity. This Fulbright Fellowship will combine unique Australian expertise in atom-light interactions with world-leading experience in mixing multi-coloured light fields at Columbia University to enable the development of next-generation secure communications by dramatically increasing the distance of quantum-secured fibre information networks. More information available here.
  • Australia-Germany Joint Research Co-Operation Scheme (2019-2020)
    • Title: Quantum Simulations with Stationary Light in Hollow Fibres
    • Chief Investigators: B. M. Sparkes, A. N. Luiten, C. Perrella, P. S. Light, J. P. Hedger, P. Windpassinger
    • Funding: $22,500
    • Summary: By engineering “crystals of light” through enhanced atom-light interactions within the hollow core of special optical fibres, this Project will realise a new, improved form of quantum simulator that will be flexible, scalable and easy to read. This is important as a quantum simulator will allow us to study crucial quantum systems that cannot be studied via conventional physics.

    • Title: Fully-Integrated Fibre-Based Platform for a Quantum Information Network
    • Chief Investigator: B. M. Sparkes 
    • Funding: $360,000
    • Summary: This Project will implement novel quantum information storage protocols in the hollow-core fibre systems available at the Institute for Photonics and Advanced Sensing.
  • ARC Linkage Project LP150101188 (2015-2018)
    • Title: Optical Technology for Quantum Science
    • Chief Investigators: R. E. Scholten, R. Starr, N. P. Robins, M. Biercuk, E. Huntington, B. M. Sparkes
    • Funding: $350,000
    • Summary: The Project is developing precision instrumentation both to enhance scientific research and to strengthen ties with industry through commercialisation.
