    How AI engines see them

    Recognized by 5 of 5 measured engines. Updated 2026-10-26

    All five engines name Preskill as a Caltech theoretical physicist working on quantum information. They agree on his links to quantum error correction and fault tolerance and on the NISQ term. Copilot adds that he co-developed the Gottesman Kitaev Preskill code and tied quantum information to black hole questions. Perplexity adds the accuracy threshold theorem worked out with Daniel Gottesman. ChatGPT adds that he founded the Caltech Institute for Quantum Information in 2000 and that his lecture notes became a common reference. Cited pages come mostly from caltech.edu, with Wikipedia and arXiv also appearing.
