Per Delsing

Per Delsing (born 1959) is a Swedish physicist and professor in experimental physics at Chalmers University of Technology.

Career Per Delsing studied engineering physics at Lund University, where he graduated with a master of science in engineering (Swedish: civilingenjörsexam) in 1984. In 1991, he was appointed assistant professor at the University of Gothenburg, where he became associate professor in 1994. Since 1997, he has been a full professor in experimental physics at Chalmers.

In recent years, Delsing's research has been focusing on quantum information in superconducting qubits. In 2018, he became the director of the largest Swedish effort in quantum technology – the Wallenberg Center for Quantum Technology (WACQT) – which he led until the end of 2024

Delsing has, as of 2025, more than 130 peer-reviewed scientific publications , over 17000 citations, and an h-index of 69.

Awards and distinctions Delsing is a member of the Royal Swedish Academy of Engineering (IVA) since 1999 , and of the Royal Swedish Academy of Sciences (KVA) since 2007. He was also a member of the Nobel Committee for Physics between 2007 and 2015, and its chairman in 2014.

In 2009, Delsing was awarded the Gustaf Dalén Medal by Chalmers University of Technology.

In 2015, he was granted the American Physical Society (APS) fellowship by the Division of Condensed Matter Physics "for pioneering research on the physics of single-electron devices, superconducting circuits, and microwave photonics". In the same year, he became a distinguished professor appointed by the Swedish Research Council (VR).
