Quantum random walk is the quantum counterpart of a classical random walk. The classical
random walk concept has long been used as a computational framework for designing …

Quantum walks, the quantum mechanical counterpart of classical random walks, is an
advanced tool for building quantum algorithms that has been recently shown to constitute a …

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 study the behavior of tunable one-dimensional discrete-time quantum walk (DTQW) in
the presence of decoherence modeled by the flip-bit noise channel. By varying the noise …

Quantum computation, one of the latest joint ventures between physics and the theory of
computation, is a scientific field whose main goals include the development of hardware and …

We present a generalized version of the discrete time quantum walk, using the SU (2)
operation as the quantum coin. By varying the coin parameters, the quantum walk can be …

Open quantum systems is the study of quantum dynamics of the system of interest, taking
into account the effects of the ambient environment. It is ubiquitous in the sense that any …

We study the asymptotic position distribution of general quantum walks on a lattice,
including walks with a random coin, which is chosen from step to step by a general Markov …

The problem of defining quantum non-Markovianity has proven elusive, with various in-
equivalent criteria put forth to address it. The concept of CP-indivisibility and the hierarchy of …

Quantum non-Markovianity of a quantum noisy channel is typically identified with
information backflow or, more generally, with departure of the intermediate map from …
