Rose Ahlefeldt

Dr. Rose Ahlefeldt is a Senior Research Fellow at The Australian National University's Department of Quantum Science & Technology, affiliated with the ARC Centre of Excellence for Quantum Computation and Communication Technology. Her research focuses on quantum information processing, with emphasis on spin coherence in rare-earth ions and silicon-based quantum systems. She collaborates extensively with leading researchers like Prof. Matthew Sellars and Prof. John Close.

Key contributions include advancing Erbium-doped silicon for ultra-long spin coherence (exceeding 10-hour nuclear spin storage) and developing photon echo memory technologies. Her work integrates experimental physics with computational modeling, targeting scalable quantum devices. She has published widely on topics like Zeeman/hyperfine interactions, optical spectroscopy of single ions, and material engineering for quantum applications.

Notable projects include optimizing stoichiometric rare-earth crystals for quantum communication and exploring telecom-compatible quantum memory systems. Her research bridges fundamental physics with applied quantum technologies, addressing challenges in coherence time extension and noise reduction.

Dr. Ahlefeldt maintains active collaborations within the ANU Research School of Physics and has been involved in multiple ARC-funded projects. Her work demonstrates a strong focus on translating theoretical concepts into experimental quantum systems with real-world applicability.
