A Novel Algorithm of Quantum Random Walk in Server Traffic Control and Task Scheduling
Journal of Applied Mathematics, 2014 A quantum random walk optimization model and algorithm in network cluster server traffic control and task scheduling is proposed. In order to solve the problem of server load balancing, we research and discuss the distribution theory of energy field in ...

Revisiting one-dimensional discrete-time quantum walks with general coin
Physics Open, 2023 Quantum walk (QW) is the quantum analog of the random walk. QW is an integral part of the development of numerous quantum algorithms. Hence, an in-depth understanding of QW helps us to grasp the quantum algorithms. We revisit the one-dimensional discrete-

Measurement-induced quantum walks on an IBM quantum computer
Physical Review Research, 2023 We study a quantum walk of a single particle that is subject to stroboscopic projective measurements on a graph with two sites. This two-level system is the minimal model of a measurement-induced quantum walk.

Open Quantum Random Walks [PDF]
Journal of Statistical Physics, 2012 A new model of quantum random walks is introduced, on lattices as well as on finite graphs. These quantum random walks take into account the behavior of open quantum systems. They are the exact quantum analogues of classical Markov chains. We explore the "quantum trajectory" point of view on these quantum random walks, that is, we show that measuring ...

Journal of Physics A: Mathematical and Theoretical, 2010 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 \textit{Levy-like particle}that moves along a lattice through hopping scale-free while interacting with a thermal bath of oscillators.

Floquet-engineered quantum walks [PDF]
Scientific Reports, 2020 AbstractThe quantum walk is the quantum-mechanical analogue of the classical random walk, which offers an advanced tool for both simulating highly complex quantum systems and building quantum algorithms in a wide range of research areas. One prominent application is in computational models capable of performing any quantum computation, in which ...

Localized quantum walks as secured quantum memory [PDF]
, 2015 We show that a quantum walk process can be used to construct and secure quantum memory. More precisely, we show that a localized quantum walk with temporal disorder can be engineered to store the information of a single, unknown qubit on a compact ...

Journal of Physics A: Mathematical and Theoretical, 2017 By adding an extra Hilbert space to Hadamard Quantum Walk on Cycles (QWC), we presented a new type of QWCs called M\"obius Quantum Walk (MQW). The new space configuration enables the particle to rotate around the axis of movement. We defined factor $\alpha$ as the M\"obius factor which is number of rotations per cycle.
