Dr. Ryan Mann

• Postdoctoral Fellow
• University of Technology Sydney

Ryan completed his master’s in physics before undertaking a PhD in Computer Science at the University of Technology Sydney. Here, he specialised in the complexity-theoretic and algorithmic aspects of quantum systems.

Following his PhD, he has held postdoctoral positions in Mathematics at the University of Bristol and in Computer Science at UTS. He is currently based at the FLiQC UTS node, where his Postdoc research explores the computational complexity of quantum systems. His work focuses on distinguishing systems that demonstrate quantum advantage from those that can be efficiently simulated on classical computers. For systems exhibiting quantum advantage, Ryan develops formal complexity-theoretic frameworks. For systems that are classically simulable, he designs and analyses efficient classical algorithms. Reflecting on his path into quantum computing, Ryan explains that his interest stemmed from a broader curiosity about the foundations of physics and a desire to study theoretical ideas in a rigorous and concrete way. He notes that quantum information theory appealed to him because it provides a precise framework for examining fundamental questions about quantum systems, including their limits and the range of behaviours they can exhibit.
