Xanthe Croot

The University of Sydney is offering a 3-year postdoctoral position in experimental particle physics and quantum computing, supervised by Dr. Laura Manenti. The research focuses on understanding and mitigating the effects of ionizing radiation on superconducting quantum computers. The successful candidate will lead experimental efforts on superconducting qubit measurements, develop a cryogenic cosmic-ray detector, operate dilution refrigerators, and nanofabricate radiation-resilient qubit designs. This hands-on role sits at the intersection of particle physics and quantum computing, providing opportunities to collaborate with Xanthe Croot's Superconducting Quantum Circuits Lab and Andrew Doherty's quantum theory group at the University of Sydney. Industry collaboration with Rigetti Computing offers access to advanced quantum processors. The position is fully funded by an ARC Discovery Project, with a total project budget of approximately AUD $800,000. The salary range is AUD $118,000–$136,000 per year plus 17% superannuation. The appointment is for three years, with a flexible start date around July 2026. Applicants must have a PhD in experimental physics or a related field, with preferred experience in superconducting qubit measurements, quantum sensors, cryogenic instrumentation, nanofabrication, or particle/radiation detection. The application deadline is March 15, 2026. To apply, candidates should use the University of Sydney's online application portal. Prospective applicants attending the APS March Meeting 2026 are encouraged to contact Dr. Manenti to arrange an in-person meeting. This position offers a unique opportunity to work at the forefront of quantum technology research in a collaborative and well-funded environment.
