"Quantum Entanglement Through the Lens of Complexity Theory and Cryptography" Thomas Vidick, Assistant Professor of Computing and Mathematical Sciences, performs research at the boundary of computer science and quantum information theory. A lot of his work revolves around the computational aspects of quantum entanglement, a key “spooky” phenomenon in quantum mechanics. He likes to explore the properties of entanglement by asking questions: how can entanglement be used? What consequences can it have in complexity theory? Can it be harnessed to develop new secure schemes for cryptography?
Vidick’s work in cryptography considers the challenges of developing cryptosystems, and more generally network protocols, that rely on the use of quantum devices (for improved efficiency, or security) but whose correctness can be certified without the need to rely on the trustworthiness of the quantum devices.
The Caltech Alumni Association held a day-long event to explore the ways in which computational thinking at Caltech is disrupting science and engineering, creating entirely new disciplines with "CS+X". From developing new paradigms for computation—quantum computing and DNA computing—to pushing the boundaries of machine learning and statistics in ways that transform fields like astronomy, chemistry, neuroscience, and biology, Caltech faculty are pioneering new disciplines at the interface of computer science, and science and engineering.
