Welcome to PSI, the largest research institute for natural and engineering sciences in Switzerland.
Recent highlights from our research
Faster, more precise, more reliable – the future of manufacturing
Advanced manufacturing means using state-of-the-art production methods. Researchers at PSI are helping to make techniques such as 3D printing more reliable and to advance the miniaturisation of high-performance chips.
Correcting quantum errors with neutral-atom architectures
Wenchao Xu talks about the benefits and challenges of building quantum computers from neutral atoms.
Aluminium made visible
PSI researchers have for the first time determined the exact position of the aluminium atoms in zeolites, which make these materials such good catalysts.
