Thomas Vidick


  • Fellow
  • CIFAR Azrieli Global Scholar 2017-2019
  • Quantum Information Science




Thomas Vidick’s research is 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 Vidick has made important contributions to the field of device-independent cryptography.
