Oleksandr Kyriienko is a Ukrainian theoretical physicist working in the areas of quantum computing and quantum optics. He has finished MSc studies at the National University of Kyiv, and in 2010 went for a PhD programme at the University of Iceland. Oleksandr has completed the PhD in quantum optics in 2014, and from 2014 to 2017 has worked as a postdoctoral researcher at the Niels Bohr Institute in Copenhagen, Denmark. During this time, he concentrated on developing quantum simulation approaches. In 2017 he has received a 2-year fellowship to conduct an independent research programme at NORDITA (Nordic Institute for Theoretical Physics) in Stockholm, Sweden. At that point Dr Kyriienko started developing quantum algorithms for emerging near-term quantum computers.
He has moved to the University of Exeter as a Lecturer (Assistant Professor) in the end of 2019, and started building a research group working on different subjects of quantum technology. Concentrating on the field of quantum scientific computing and machine learning, together with industrial collaborators he has proposed various protocols for solving PDEs and generative modelling. As of 2025 he is a Chair in Quantum Technologies at the University of Sheffield and Director of the Sheffield Quantum Centre. Oleksandr continues to lead research in quantum SciML and simulation.
