Stephanie Wehner is a physicist and computer scientist at the Centre for Quantum Technologies, National University of Singapore, born in Wuerzburg, Germany.[1] 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.[1][2] Since 2010 Wehner is an assistant professor in the department of computer science at the National University of Singapore and a Principal Investigator at the Centre for Quantum Technologies.

Together with Jonathan Oppenheim she discovered that the amount of non-locality in quantum mechanics is limited by the uncertainty principle.[3][4][5] She is also known for introducing the noisy-storage model in quantum cryptography.[6]

Before academia Wehner was involved in computer security, for example kernel rootkits,[7] and for a while worked as a professional hacker.[1]
