David Schlegel is a PhD student contributor to Physics World, conducting research in the Laboratory of Theoretical Physics of Nanosystems at the Swiss Federal Institution of Technology (EPFL). He specializes in bosonic quantum error correction and the simulation of open quantum systems. With his work, he tries to make quantum information more robust against errors, a crucial ingredient for large-scale fault-tolerant quantum computers. David studied physics and philosophy at the University of Göttingen, Germany, after which he started his PhD at EPFL. Outside of research, he enjoys hiking, running, cycling and reading about science.
