Draft:Jan Berend Meijer

• Comment: Most of the highly cited pubs are team efforts, so do not count fully. Does he have national or international awards, see WP:NPROF. Without those the page is not convincing. And....details of the COI are required. Ldm1954 (talk) 04:30, 12 July 2026 (UTC)

Jan Berend Meijer is a German physicist and university professor. Since 2013, he has served as professor at Leipzig University, where he heads the Applied Quantum Systems department at the Felix Bloch Institute for Solid State Physics.

Education and career

Meijer received his Ph.D. degree in physics in 1997 from the University of Münster. From 1997 to 2004, he worked as a senior scientist at Ruhr University Bochum. From 2004 to 2012, he served as managing director of the Central Unit for Ion Beams and Radionuclides (RUBION) at Ruhr University Bochum. In 2013, Meijer joined Leipzig University, where his research has focused on applied quantum systems and quantum technologies. In 2021, he co-founded SaxonQ, a Leipzig-based quantum computing company developing room-temperature quantum computers based on nitrogen-vacancy centers in diamond.

Research

Meijer's research focuses on the investigation and modification of surfaces and solids at the atomic scale using ion beams. His work includes the implantation of ions with kinetic energies ranging from a few kiloelectronvolts to several megaelectronvolts into solids with nanometre precision. A central topic of his research is deterministic single-ion implantation, which aims at the precise positioning of individual foreign atoms in solids for applications in quantum technologies. This work is carried out in cooperation with the Leibniz Institute of Surface Engineering in the Leibniz Joint Lab “Single Ion Implantation”. Meijer and his research group have contributed to the controlled generation of nitrogen-vacancy centers in diamond. These color centers are considered promising systems for quantum sensing and quantum computing. In 2019, Meijer and colleagues published a method in Nature Communications for producing such color centers with a yield of around 75 percent. In a public demonstration, the researchers used a red diamond produced in this way as a highly sensitive magnetic sensor to detect the electromagnetic signals of an electric guitar. The long-term aim of the Applied Quantum Systems group is the integration of a color-center-based coprocessor on a chip with a classical computer. This work is supported by collaborative projects including BMBF CoGeQ and the EU project Mastro.
