We extend to the gamut of functional forms of the probability distribution of the time-dependent step-length a previous model dubbed Elephant Quantum Walk, which considers a uniform distribution and yields hyperballistic dynamics where the variance grows cubicly with time, σ2 ∝ t3, and a Gaussian for the position of the walker. We investigate this proposal both locally and globally with the results showing that the time-dependent interplay between interference, memory and long-range hopping… 
Scaling exponent analysis and fidelity of the tunable discrete quantum walk in the noisy channel
Abstract We studied the behavior of tunable one-dimensional discrete-time quantum walk (DTQW) in the presence of decoherence, modeled as a noisy quantum channel with bit-flip, phase-flip, and general

Abstract We consider a discrete time quantum walker in one dimension, where at each step, the step length l is chosen from a distribution P ( l ) ∝ l − δ − 1 with l ≤ l m a x . We evaluate the
Persistent quantum walks: Dynamic phases and diverging timescales
A discrete time quantum walk is considered in which the step lengths are chosen to be either $1$ or $2$ with the additional feature that the walker is persistent with a probability $p$. This implies
Collective treadmilling in fire ant rafts permits sustained protrusion growth
Condensed active matter is exemplary for its capacity to morph and exhibit internal flows despite remaining cohered. (1) To facilitate understanding of this ability, we investigate the cause of
Negative correlations can play a positive role in disordered quantum walks
The results show that negatively correlated disorder plays a more important role in quantum entanglement than it has been assumed in the literature.
Quantum walks with sequential aperiodic jumps.
Fingerprints of the aperiodicity in the hoppings are found when distributional measures such as the Shannon and von Neumann entropies, the Inverse Participation Ratio, the Jensen-Shannon dissimilarity, and the kurtosis are computed, which allow assessing informational and delocalization features arising from these protocols and understanding the impact of linear and nonlinear correlations of the jump sequence in a quantum walk as well.
Localization in Quantum Walks with a Single Lattice Defect: A Comparative Study
We study how a single lattice defect in a discrete time quantum walk affects the return probability of a quantum particle. This defect at the starting position is modeled by a quantum coin that is
Parrondo's paradox in quantum walks with time-dependent coin operators.
We show that a Parrondo paradox can emerge in two-state quantum walks without resorting to experimentally intricate high-dimensional coins. To achieve such goal we employ a time-dependent coin


The Elephant Quantum Walk
We explore the impact of long-range memory on the properties of a family of quantum walks in a one-dimensional lattice and discrete time, which can be understood as the quantum version of the
One-dimensional quantum walks subject to next-nearest-neighbour hopping decoherence
The diffusive behaviours of quantum walks are sub-ballistic and the distributions of position exhibit three peaks when the decoherence effects only come from the bilateral hopping operation, quite different from those of the previous non-unitary quantum walks.
Two-dimensional quantum walk under artificial magnetic field
We introduce the Peierls substitution to a two-dimensional discrete-time quantum walk on a square lattice to examine the spreading dynamics and the coin-position entanglement in the presence of an
Enhanced non-Markovian behavior in quantum walks with Markovian disorder
It is shown that the information backflow that quantifies memory effects can be enhanced when the particle is subjected to uncorrelated static or dynamic disorder and the presence of disorder in the system leads to localization effects in 1-dimensional quantum walks.
Inhibition of spreading in quantum random walks due to quenched Poisson-distributed disorder
We consider a quantum particle (walker) on a line who coherently chooses to jump to the left or right depending on the result of toss of a quantum coin. The lengths of the jumps are considered to be
The quantum Levy walk
We introduce the quantum Levy walk to study transport and decoherence in a quantum random model. We have derived from second-order perturbation theory the quantum master equation for a Levy-like
Quantum walk with jumps
Abstract. We analyze a special class of 1-D quantum walks (QWs) realized using optical multi-ports. We assume non-perfect multi-ports showing errors in the connectivity, i.e. with a small probability
Dynamically disordered quantum walk as a maximal entanglement generator.
We show that the entanglement between the internal (spin) and external (position) degrees of freedom of a qubit in a random (dynamically disordered) one-dimensional discrete time quantum random walk

We consider a discrete-time random walk where the random increment at time step t depends on the full history of the process. We calculate exactly the mean and variance of the position and discuss
Entangling power of disordered quantum walks
We investigate how the introduction of different types of disorder affects the generation of entanglement between the internal (spin) and external (position) degrees of freedom in one-dimensional
