Jan-Åke Larsson

Jan-Åke Larsson is a Professor and Head of Department at the Department of Electrical Engineering (ISY) at Linköping University, Sweden. His academic career spans over two decades, with positions progressing from PhD student to Professor and department leadership. He has made significant contributions to quantum information science, particularly in quantum cryptography, quantum computing foundations, and Bell inequality tests.

• PhD in Applied Mathematics, Linköping University (2000)
• Docent in Applied Mathematics, Linköping University (2003)

Professor Larsson's research primarily focuses on quantum technology, quantum information theory, and the foundations of quantum mechanics. His work explores the resources available to quantum computers that enable quantum advantage, the security of quantum cryptography systems (particularly classical subsystems), and fundamental questions of locality and contextuality in quantum mechanics. He has pioneered research in loophole-free Bell tests and developed theoretical frameworks for understanding quantum contextuality.

His recent publications demonstrate a continued focus on foundational aspects of quantum mechanics while expanding into quantum computing algorithms and resource optimization. There's a clear trend toward addressing practical challenges in quantum computing implementation while maintaining a strong theoretical foundation in quantum information science.

• Contributed to Nobel Prize-winning research on quantum entanglement (2022 Physics Nobel)
• Key contributor to the "Big Bell Test" experiment published in Nature (2018)
• Significant contributions to loophole-free Bell inequality tests

Professor Larsson has supervised multiple PhD students to completion, including Niklas Johansson (2022), Jonathan Jogenfors (2017), and Aysajan Abidin (2013), with Christoffer Hindlycke currently completing his PhD. His research has been supported by grants from the Swedish Research Council and other national and international funding bodies. He has collaborated extensively with leading quantum research groups worldwide, including those led by Nobel Laureate Anton Zeilinger.

As Head of Department at ISY, Professor Larsson oversees one of Sweden's leading electrical engineering research and education units. He is actively involved in the Information Coding (ICG) research group, which focuses on quantum information, cryptography, and communication theory.
