Machine translation, like DeepL or Google Translate, is a useful starting point for translations, but translators must revise errors as necessary and confirm that the translation is accurate, rather than simply copy-pasting machine-translated text into the English Wikipedia.
Do not translate text that appears unreliable or low-quality. If possible, verify the text with references provided in the foreign-language article.
You must provide copyright attribution in the edit summary accompanying your translation by providing an interlanguage link to the source of your translation. A model attribution edit summary is Content in this edit is translated from the existing German Wikipedia article at [[:de:Matthias Troyer]]; see its history for attribution.

Matthias Troyer (born 1968) is an Austrian physicist and computer scientist specializing in quantum computing. He is also Technical Fellow and Corporate Vice President of Quantum at Microsoft.[3][4]
Education and career
Troyer was born April 18, 1968 in Linz, Austria. He completed University Studies in Technical Physics at the Johannes Kepler Universität Linz, Austria, in 1991 as well as Diploma in Physics and Interdisciplinary PhD thesis at the ETH Zürich Swiss Federal Institute of Technology Zurich in 1994.[5][6]
His PhD on “Simulation of Constrained Fermions in Low-Dimensional Systems” was completed under Diethelm Wurtz and Thomas Maurice Rice, earning the ETH medal for outstanding doctoral thesis [7]
Following earning his PhD he spent three years as a fellow of the Japanese Society for the Promotion of Sciences at the Institute for Solid State Physics. In 2000, he was awarded an assistant professorship of the Swiss National Science Foundation.[7]
In June 2002 he became Associate Professor at the ETH Zurich and in 2005 Full Professor of Computational Physics before joining Microsoft’s quantum computing program in 2017.[8] He is also an Affiliate Professor at the University of Washington.[9]
He initiated the open-source project ALPS (Algorithms and Libraries for Physics Simulations), to make algorithms in many-body systems accessible to the scientific public.[10]
Troyer develops practical algorithms and applications for quantum computing with high performance computing, including library design, simulations of quantum devices, chemical reactions, neural networks and AI.[11][12][13][6][8][14] He also studies simulation algorithms for quantum many body systems, quantum phase transitions, strongly correlated materials, and ultracold quantum gases.[1][7]
In 2015, he was awarded the Aneesur Rahman Prize for Computational Physics of the American Physical Society for pioneering work in several seemingly inaccessible areas of the quantum mechanical many-body problem and for making efficient, sophisticated computer programs accessible to the scientific community.[1][8]
He is also the president of the Aspen Center for Physics and has been a member since 2004. He is also a board member of the Washington State Academy of Sciences.[15][16]
Troyer received the gold medal at the International Chemistry Olympiad in 1986 and the silver medal in 1985.[1][17][18]
