## Abstract We consider quantum random walks (QRW) on the integers, a subject that has been considered in the last few years in the framework of quantum computation. We show how the theory of CMV matrices gives a natural tool to study these processes and to give results that are analogous to those

While it is straightforward to simulate a very general class of random processes space-efficiently by non-unitary quantum computations (e.g., quantum computations that allow intermediate measurements to occur), it is not currently known to what extent restricting quantum computations to be unitary a
## Abstract Starโbranched random walks with 3, 4, 6, 8 and 12 arms (the total chainโlength ranging from __N__ = 49 to 1925) have been produced and analysed with respect to their instantaneous shape. The shortโchain behaviour of nonreversal random walk stars (NRRWs) embedded in various lattices is c
