Quantum walks can be considered as a generalized version of the classical random walk.
There are two classes of quantum walks, that is, the discrete-time (or coined) and the …

We consider a graph with a single quantum system at each node. The entire compound
system evolves in discrete time steps by iterating a global evolution U. We require that this …

New exact results are given for the interior Casimir energies of infinitely long waveguides of
triangular cross section (equilateral, hemiequilateral, and isosceles right triangles). Results …

The quantum walk is a generalization of classical random walks. Considerable work has
been recently investigated on quantum walks in connection with quantum computing. The …

Quantum cellular automata (QCA) consist of an array of identical, finite dimensional,
quantum systems. These evolve in discrete time steps according to a causal, shift-invariant …
