Stephanie Dorothea Christine Wehner (born 8 May 1977 in Würzburg)[1] is a German physicist and computer scientist.
She is the Roadmap Leader of the Quantum Internet and Networked Computing initiative[2] at QuTech, Delft University of Technology.[3] She is also known for introducing the noisy-storage model in quantum cryptography.[4] Wehner's research focuses mainly on quantum cryptography and quantum communications.
Wehner, together with Jonathan Oppenheim, discovered that the amount of non-locality in quantum mechanics is limited by the uncertainty principle.[5][6][7]
