    WITS Node Seminar: Prof Francesco Petruccione (UKZN)

    Good morning All,

    The National Institute for Theoretical Physics, and the Centre for Theoretical Physics, School of Physics, would like to invite to its coming talk in the theoretical physics seminar series, entitled:

    "Open Quantum Walks"

    to be presented by Prof. Francesco Petruccione (University of KwaZulu-Natal)

    Abstract: Recently, a formalism for discrete time open quantum walks was introduced [1]. The formalism is similar to the formalism of quantum Markov chains and rests upon the the implementation of appropriate completely positive maps. Open Quantum Walks include classical random walks and a connection to unitary quantum walks can be established. Furthermore, Open Quantum Walks allow for an unravelling in terms of quantum trajectories. It was shown, that Open Quantum Walks can perform universal quantum computation and can be used for quantum state engineering [2]. Open Quantum Walks can be derived microscopically and be successfully applied to the modelling of transport phenomena in Quantum Biology.
