This PhD scholarship opportunity at the University of Newcastle focuses on the development of error correction codes for free-space quantum communications, with a particular emphasis on continuous variable quantum key distribution (CV-QKD). The project aims to advance new analysis, design, and decoding methods for error correction codes, specifically targeting information reconciliation in quantum communication systems. Research will involve creating innovative QKD methods that can adapt to rapid changes in turbulence, interference, absorption, and diffraction encountered during satellite orbital paths, ensuring robust and secure quantum communication. Key objectives include designing rate-less error correction schemes that dynamically adjust code rates to the channel conditions, enabling zero-word error rate decoding while minimizing decoding complexity. The successful candidate will work alongside world-leading researchers in error correction codes, benefiting from strong mentorship, comprehensive research support, and professional development opportunities. Collaboration with leading universities and external organizations is also a feature of this program. The scholarship is funded by the Australian Research Council (ARC) and provides a living allowance of $37,440 per annum (2025 rate), indexed annually, plus a tuition fee scholarship for 3.5 years and up to $1,500 relocation allowance. The position is open to domestic students, and applicants from electrical, electronics, computer systems, or telecommunications engineering backgrounds are encouraged to apply. The scholarship will be awarded subject to the grant/funding being fully established. Eligibility requires meeting the minimum criteria for PhD admission at the University of Newcastle. Interested applicants should prepare an email expressing their interest, including scanned academic transcripts, CV, a brief statement of research interests, and a proposal specifically linked to the research project. Applications must be submitted by 5pm on 31 December 2025 to the provided contact email. For more information and to apply, visit the official scholarship page.
