Macquarie University has strengthened its position in quantum computing research through a new strategic collaboration with global quantum technology company BTQ Technologies, with an agreement that commenced 1 June, 2024.

The partnership has already yielded significant outcomes, including successful work on Quantum Proof-of-Work (QPoW), a way to integrate quantum samplers into blockchain technologies to slash energy consumption.

The new phase of research will focus on developing quantum software and securing communications against future quantum computer threats. The research also aims to enhance speed, security, and energy efficiency in mission-critical networks.

The partnership comes at a crucial time, as organisations worldwide race to prepare for “Q-Day” - when quantum computers could potentially break current encryption standards. Recent US government requirements now mandate post-quantum secure cryptography for sensitive contracts, underlining the growing importance of quantum-safe communication solutions.

Leading the research team are Professor Gavin Brennen, who also serves as Director of BTQ AU, and Dr Gopikrishnan Muraleedharan, both from the School of Mathematical and Physical Sciences. The project will include several Sydney Quantum Academy PhD students, supported by CSIRO’s Creating the Next Generation of Quantum Technology Specialists program.

“Collaborating with BTQ Technologies offers a unique opportunity to address the pressing security challenges posed by the advent of large-scale quantum computers,” said Professor Brennen.

“BTQ was founded by post-quantum security experts and its dedication to tackling quantum security threats aligns perfectly with our mission at Macquarie.”

The collaboration brings substantial benefits to Macquarie’s research ecosystem. A CSIRO-funded PhD position starting in February 2025, co-supervised by Dr. Hassan Asgar from Computing, will strengthen interdisciplinary connections via Macquarie’s Future Communications Research Centre.

The partnership also includes internship opportunities at BTQ Technologies, so students can work alongside industry leaders and academic experts.

Professor Dan Johnson, Pro Vice-Chancellor (Research, Innovation and Enterprise) at Macquarie, said the partnership brings practical benefits in both research and education. “This collaboration not only strengthens our quantum computing capabilities but also provides valuable industry experience for our PhD students.”
