  1. Nov. 13, 2020Collaborating to advance quantum technologies in Canada and the UK
    A quantum key distribution setup

    Earlier this year, Canada and the United Kingdom (UK) joined together to put a call out for proposals of collaborations between leading-edge scientists and potential innovative users from industry and government sectors to accelerate the development of quantum technologies.

  2. Nov. 12, 2020Unsolved puzzles
    Rose McCarty

    “When I was a kid, I always begged my parents to buy me those little Mind Benders puzzles,” remembered Rose McCarty. “My favorite puzzles were the ones that were so difficult that I wasn’t sure whether or not I could actually solve them. At Waterloo Math, I’m the one coming up with different puzzles to solve. I have an opportunity to tackle big, imprecise, unwieldly problems that determine what my field will look like in 20 years.”

  3. Oct. 30, 2020A secret hero's cyber legacy
    Bill Tutte

    Craig Daniels, in an article for Communitech News, traces the rise of the cybersecurity industry in Waterloo, from Bill Tutte's work at Bletchley Park during the Second World War, to the formation of Certicom Corp. by Professors Gord Agnew, Ron Mullin and Scott Vanstone, to the present time.

  1. Dec. 3, 2020Algebraic Combinatorics Seminar - Loïc Foissy

    Title: Twisted Hopf algebras

    Speaker: Loïc Foissy
    Affiliation: Université du Côte d'Opale
    Zoom: Contact Karen Yeats


    A twisted Hopf algebra is a Hopf algebra in the category of linear species. The Fock functors allow to recover "classical" Hopf algebras from twisted ones. Numerous constructions and results can be lifted to the level of twisted bialgebras, such that cofreeness, shuffle and quasi-shuffles products, etc.
