Dynamical kickback and non commuting impurities in a spin chain
Diego de Falco, Dario Tamascelli
In an interacting continuous time quantum walk, while the walker (the cursor) is moving on a graph, computational primitives (unitary operators associated with the edges) are appli…

Quantum walks: a Markovian perspective
Diego de Falco, Dario Tamascelli
For a continuous-time quantum walk on a line the variance of the position observable grows quadratically in time, whereas, for its classical counterpart on the same graph, it exhib…
