Stephanie Wehner is a physicist and computer scientist at QuTech, Delft University of Technology, born in Wuerzburg, Germany. She studied at the University of Amsterdam and obtained her Ph.D. at CWI, before moving to Caltech as a postdoctoral researcher under John Preskill. From 2010 to 2014, Wehner was an assistant professor and later associate professor at the department of computer science at the National University of Singapore and a Principal Investigator at the Centre for Quantum Technologies. From 2014, she is an associate professor at QuTech, Delft University of Technology.
Together with Jonathan Oppenheim she discovered that the amount of non-locality in quantum mechanics is limited by the uncertainty principle. She is also known for introducing the noisy-storage model in quantum cryptography.
Before academia Wehner was involved in computer security, for example kernel rootkits, and for a while worked as a professional hacker.
