An introduction to quantum annealing
Diego de Falco, Dario Tamascelli
Quantum Annealing, or Quantum Stochastic Optimization, is a classical randomized algorithm which provides good heuristics for the solution of hard optimization problems. The algori…
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…
Entropy generation in a model of reversible computation
Diego de Falco, Dario Tamascelli
We present a model in which, due to the quantum nature of the signals controlling the implementation time of successive unitary computational steps, \emph{physical} irreversibility…
Grover's algorithm on a Feynman computer
Diego de Falco, Dario Tamascelli
We present an implementation of Grover's algorithm in the framework of Feynman's cursor model of a quantum computer. The cursor degrees of freedom act as a quantum clocking mechani…
Speed and entropy of an interacting continuous time quantum walk
Diego de Falco, Dario Tamascelli
We present some dynamic and entropic considerations about the evolution of a continuous time quantum walk implementing the clock of an autonomous machine. On a simple model, we stu…
