The Prize recognises Professor Popescu’s influential work on nonlocality, entanglement, and the quantum foundations of statistical mechanics. His research interest lies in investigating fundamental aspects of quantum physics to gain a better understanding of the seemingly paradoxical nature of quantum behaviour. This has led him to develop some of the central concepts of the emerging field of quantum information and computation.
