Philip Walther received his PhD degree in Physics from the University of Vienna in 2005. After 3 year as a postdoctoral researcher at Harvard University, he returned to the University of Vienna in 2008, where he is a Professor of Physics since 2015. His research is dedicated to the development of advanced quantum technology for applications in quantum information processing and for investigations in quantum science. The experiments are focused on photonic quantum computation and quantum simulation as well as quantum foundations such as indefinite causal structures and the measurement of weak gravitational effects on single photons using table-top setups. Prof.Walther has authored/co-authored more than 80 publications in international journals and given more than 130 invited talks at international conferences. He is Fellow of the American Physical Society (APS) and the Optical Society of America (OSA).
