Thomas Vidick’s research is situated at the interface of theoretical computer science, quantum information and cryptography. He is interested in applying techniques from computer science, such as complexity theory, to study problems in quantum computing. He has investigated the role of entanglement in multi-prover interactive proof systems and obtained the first substantial computational hardness results on the power of entangled provers. Entanglement also plays a major role in quantum cryptography, and he has made important contributions to the field of device-independent cryptography. He is also interested in using quantum information theory to shed new light on fundamental techniques in theoretical computer science such as semidefinite programming and approximation algorithms.

Vidick received a B.A. in pure mathematics from Ecole Normale Superieure in Paris, a Masters in Computer Science from Universite Paris 7 and a Ph.D. from UC Berkeley. His Ph.D. thesis was awarded the Bernard Friedman memorial prize in applied mathematics. After a postdoctoral position at the Massachusetts Institute of Technology, supervised by Scott Aaronson, he joined the California Institute of Technology in 2014 and was named Professor of Computing and Mathematical Sciences in 2018. He is director of the Center for the Mathematics of Information (CMI). He holds visiting positions at the Centre for Quantum Technologies in Singapore and the Perimeter Institute in Waterloo. In 2017 he was named a CIFAR Azrieli Global Scholar. His paper “A multi-prover interactive proof for NEXP sound against entangled provers”, with Tsuyoshi Ito, was co-awarded the best paper award at FOCS’12.

You can see me talk about my research in the following recorded talks.

General-audience talks


  • At QIP’19 in Boulder, Colorado I gave a 3-hour tutorial on the topic of “Verification of Quantum Computation”: see part 1 and part 2. Slides for the tutorial are available in ppsx and (without the animations) pdf.
