Introduction to Quantum Cryptography

Thomas Vidick is Professor in the Department Computer Science and Applied Mathematics at the Weizmann Institute of Science in Israel. He received his Ph.D. from UC Berkeley in 2011, followed by two years of postdoctoral research at the Massachusetts Institute of Technology, where he worked on quantum complexity and cryptography. He joined the Computer Science Faculty at the California Institute of Technology in 2014, and became Professor in 2018. In 2022 he took a leave from CalTech to start his current position at the Weizmann Institute. Professor Vidick is best known for his research on device-independence, including the first security proof of device-independent quantum key distribution. In 2019 he received a Presidential Early-Career Award, and in 2021 was named a Simons Investigator at CalTech. In 2023 he received the Michael and Sheila Held prize from the National Academy of Sciences for his work in quantum cryptography and quantum complexity. Stephanie Wehner is Antoni van Leeuwenhoek Professor at Delft University of Technology, QuTech, and Director of the Quantum Internet Alliance. A member of the Royal Netherlands Academy of Arts and Sciences, she is also a co- founder of QCRYPT, the largest international conference in quantum cryptography. In a former life, she worked as a professional hacker. Her research is focused on manipulating the laws of quantum mechanics to construct better information networks and computer systems. Together with the Quantum Internet Alliance she is working on realizing a large-scale quantum computer network.
