Göran Johansson

Göran Johansson is a Professor of Applied Quantum Physics at Chalmers University of Technology in Gothenburg, Sweden. Since January 1, 2025, he has served as the director of the Wallenberg Centre for Quantum Technology, a major research initiative spanning from 2018 to 2030. His academic career is centered on quantum physics research with a focus on both fundamental phenomena and practical quantum technology applications.

Professor Johansson's research spans quantum physics, quantum technology, and quantum computing. He investigates fundamental quantum mechanical effects such as the dynamic Casimir effect, which describes photon generation from vacuum when a mirror accelerates at relativistic speeds. His applied research focuses on building quantum computers that leverage quantum superposition and entanglement to solve problems beyond the reach of classical supercomputers, with potential applications in drug discovery, artificial intelligence, and optimization problems like traffic planning. His work bridges theoretical quantum physics with practical implementation in superconducting circuits.

An analysis of his recent publications reveals a strong focus on quantum computing hardware, particularly superconducting qubits and quantum processors. His research addresses key challenges in quantum computing including decoherence, quantum gate fidelity, quantum error correction, and quantum state engineering. There's a clear progression toward more complex quantum systems, with recent work exploring multi-qubit gates, quantum algorithms for practical applications, and integration of quantum processors. His publications consistently appear in top physics journals including Physical Review Letters, Physical Review A/B, and npj Quantum Information.

Professor Johansson has received two significant awards for his contributions to quantum physics:

• Edlund Prize 2016 from the Royal Swedish Academy of Sciences
• Albert Wallin Science Prize 2015 from the Royal Society of Science and Letters in Gothenburg

He leads or participates in multiple major research projects including the Wallenberg Centre for Quantum Technology (2018-2030), Quantum Networks with Delay and High-Impedance Transmission Lines (2022-2025), Quantum Information with Microwaves and Surface Acoustic Waves (2018-2021), and Quantum Plasmonics (2017-2022). These projects involve collaborations with numerous researchers across Chalmers and with external partners, supported by funding from the Swedish Research Council (VR) and the Knut and Alice Wallenberg Foundation.

As director of the Wallenberg Centre for Quantum Technology, Professor Johansson oversees one of Sweden's largest quantum research initiatives, which includes a broad team of researchers working on quantum computing, quantum communication, and quantum sensing. His research group focuses on superconducting quantum circuits, exploring both fundamental quantum phenomena and practical implementations for quantum information processing. The group works extensively with microwave quantum optics and has made significant contributions to the understanding and manipulation of quantum states in superconducting systems.
