A James Scott Prize Lecture delivered by Professor Stephen Barnett.

Professor Barnett is one of the world’s most eminent scientists in the field of Quantum Optics. A previous winner of the Institute of Physics’ Maxwell Medal, he is perhaps best known for his co-discovery of the Barnett-Pegg phase operator. This established the first formally correct approach for handling both angles and phase as descriptions within quantum systems.

Still within quantum physics, Professor Barnett holds a number of patents relating to techniques for writing unbreakable codes. For a subject that is potentially beyond most people’s understanding, Professor Barnett is well known for presenting the counter-commonsense implications of quantum mechanics in an accessible and entertaining way, stripping the subject of its supporting mathematics and leaving only the essence of pure ideas.
