Per Delsing

Professor at Chalmers, Microtechnology and Nanoscience (MC2), Quantum Device Physics

Per Delsing is a full professor at Chalmers University of Technology since 1997. His research focuses on quantum properties of superconducting devices. With artificial atoms based on superconducting circuits he studies quantum optics on chip by investigating how these ”atoms" interact with microwave photons. Placing the artificial atoms on piezoelectric surfaces it is also possible to study how the atoms interact with phonons if the form of Surface Acoustic Waves (SAWs). He also studies quantum information using superconducting qubits, with the final goal to build a quantum computer.Per is teaching a course on Superconductivity and low temperature physics.Per is a member of the Royal Swedish Academy of Sciences (KVA), and of the Royal Academy of Engineering Sciences (IVA). He is also a Distinguished Professor appointed by the Swedish Research Council (VR), Fellow of the American Physical Society (APS) and a Wallenberg Scholar.
