Biography
Oscar Dahlsten, associate professor in physics, works in the field of quantum information science. His research can be divided into the categories of: (i) information thermodynamics, (ii) foundations of quantum theory, and (iii) quantum computation and machine learning. He was trained at Imperial College and worked at ETH Zurich, NUS Singapore, Oxford University and SUSTech before joining City University Hong Kong. His contributions, in collaboration with others, include showing that random quantum circuits typically generate maximal entanglement, and pioneering the single-shot approach to non-equilibrium statistical mechanics.
