Bob Coecke (born 1968) is a Belgian theoretical physicist and logician who was professor of Quantum Foundations, Logics and Structures at Oxford University till 2020, and is now Chief Scientist of Cambridge Quantum Computing. He is a pioneer of categorical quantum mechanics (now an entry in Mathematics Subject Classification 2020), Quantum Picturalism, ZX-calculus, DisCoCat model for natural language, and quantum natural language processing (QNLP). He is a founding father of the Quantum Physics and Logic community and conference series, of the Applied category theory community, conference series and diamond-open-access journal Compositionality.

Education and careerEdit
Coecke obtained his Doctorate in Sciences at the Vrije Universiteit Brussel in 1996, and performed postdoctoral work in the Theoretical Physics Group of Imperial College, London in the Category Theory Group of the Mathematics and Statistics Department at McGill University in Montreal, in the Department of Pure Mathematics and Mathematical Statistics of Cambridge University, and in the Department of Computer Science, University of Oxford.
He was an EPSRC Advanced Research Fellow at the Department of Computer Science, University of Oxford, where he became Lecturer in Quantum Computer Science in 2007, and jointly with Samson Abramsky built and headed the Quantum Group, which in 2020 had well over 50 members. In 2009, he worked as visiting scientist at the Perimeter Institute for Theoretical Physics. In July 2011, he was nominated professor of Quantum Foundations, Logics and Structures at Oxford University, with retroactive effect as of October 2010. He was a Governing Body Fellow of Wolfson College, Oxford since 2007, where he now is an Emeritus Fellow.
In January 2019 he became Senior Scientific Advisor of Cambridge Quantum Computing, and in January 2021 he resigned from his Professorship at Oxford, to become Chief Scientist of Cambridge Quantum Computing.
Coecke's research focuses on the foundations of physics, more particularly category theory, logic, and diagrammatic reasoning, with application to quantum informatics, quantum gravity, and NLP. He has pioneered categorical quantum mechanics together with Samson Abramsky, and spearheaded the development of a diagrammatic quantum formalism based on Penrose graphical notation, on which he wrote a textbook entitled Picturing Quantum Processes with Aleks Kissinger. With Ross Duncan he pioneered ZX-calculus. He pioneered the DisCoCat model for natural language, with Stephen Clark and Mehrnoosh Sadrzadeh. He also pioneered quantum natural language processing (QNLP), with Will Zeng and colleagues at Cambridge Quantum Computing.
The work of Coecke and his co-workers on the application of categorical quantum mechanics to natural language processing in computational linguistics was featured in New Scientist in December 2010. The work on quantum natural language processing was featured in the Quantum Daily in December 2020 and in PhysicsWorld in January 2021.
