  1. Sep. 28, 2017Algebraic Graph Theory Seminar - Christopher van Bommel

    Title: Quantum Walks and State Transfer

    Speaker: Christopher van Bommel
    Affiliation: University of Waterloo
    Room: MC 6486

    Abstract:

    Quantum walks are the quantum analogues of classical random walks and can be used to model quantum computations. If a quantum walker starts at a vertex of a graph and after some length of time, has probability 1 of being found at a different vertex, we say there is perfect state transfer between the two vertices.

  3. Sep. 29, 2017Tutte Colloquium - Debbie Leung

    Title: The quantum and private capacities of quantum channels, and the solution in the low-noise regime

    Speaker: Debbie Leung
    Affiliation: University of Waterloo
    Room: MC 5501

    Abstract:

    We first summarize background on the quantum capacity of a quantum channel, and explain why we know very little about this fundamental quantity, even for the qubit depolarizing channel (the quantum analogue of the binary symmetric channel) despite 20 years of effort by the community.
