چکیده
We investigate the possibility of implementing a sequence quantum walks whose probability distributions give an overall positive winning probability, while it is negative for single (Parrondo’s paradox). In particular, we have in mind experimental realization with Bose–Einstein condensate which walker’s space momentum space. Experimental problems precise implementation coin operations our discrete-time are analyzed detail. study time-dependent phase fluctuations coins as well perturbations arising from finite width condensate. confirm visibility Parrondo’s paradox experimentally available time scales up to few hundred steps walk.

Discrete-Time Quantum Walks and Graph Structures
We formulate three current models of discrete-time quantum walks in a combinatorial way. These walks are shown to be closely related to rotation systems and 1-factorizations of graphs. For two of the models, we compute the traces and total entropies of the average mixing matrices for some cubic graphs. The trace captures how likely a quantum walk is to revisit the state it started with, and the...
متن کاملCrossovers induced by discrete-time quantum walks
We consider crossovers with respect to the weak convergence theorems from a discretetime quantum walk (DTQW). We show that a continuous-time quantum walk (CTQW) and discreteand continuous-time random walks can be expressed as DTQWs in some limits. At first we generalize our previous study [Phys. Rev. A 81, 062129 (2010)] on the DTQW with position measurements. We show that the position measurem...
متن کاملScattering theory and discrete-time quantum walks
We study quantum walks on general graphs from the point of view of scattering theory. For a general finite graph we choose two vertices and attach one half line to each, and consider walks that proceed from one half line, through the graph, to the other. The probability of starting on one line and reaching the other after n steps can be expressed in terms of the transmission amplitude for the g...
متن کاملLimit theorems for discrete-time quantum walks on trees
We consider a discrete-time quantum walk Wt given by the Grover transformation on the Cayley tree. We reduce Wt to a quantum walk Xt on a half line with a wall at the origin. This paper presents two types of limit theorems for Xt. The first one is Xt as t → ∞, which corresponds to a localization in the case of an initial qubit state. The second one is Xt/t as t → ∞, whose limit density is given...
متن کاملDecoherence in Discrete Quantum Walks
We present an introduction to coined quantum walks on regular graphs, which have been developed in the past few years as an alternative to quantum Fourier transforms for underpinning algorithms for quantum computation. We then describe our results on the effects of decoherence on these quantum walks on a line, cycle and hypercube. We find high sensitivity to decoherence, increasing with the num...
