Jan-Åke Larsson

Head of Department, Professor

My research is mainly in quantum technology, quantum information theory and foundations of quantum mechanics.

Quantum Technology, quantum information theory and foundations of quantum mechanics.



Research and teaching

My main research interests are connected in various ways with quantum mechanics, and I teach cryptology, quantum information theory, and foundations of quantum theory. My current main research project is a study of the resources available to Quantum Computers, that enable the quantum advantage.

Previous research concerns the security of Quantum Cryptography, specifically the classical subsystems needed in the various proposed systems. Underlying all this is the foundations of quantum mechanics, where I study questions of locality and contextuality, see the publication list for more information.
