Quantum to classical walk transitions tuned by spontaneous emissions
Physical Review Research, 2021 We have realized a quantum walk in momentum space with a rubidium spinor Bose-Einstein condensate by applying a periodic kicking potential as a walk operator and a resonant microwave pulse as a coin toss operator. The generated quantum walks appear to be

Evolution of quantum resources in quantum-walk-based search algorithm
Results in Physics, 2023 Quantum walk is fundamental to designing many quantum algorithms. Here we consider the effects of quantum coherence and quantum entanglement for the quantum walk search on the complete bipartite graph.

Discrete-time quantum walk on complex networks for community detection
Physical Review Research, 2020 Many systems such as social networks and biological networks take the form of complex networks, which have a community structure. Community detection in complex networks is of great interest to many researchers in statistical physics and mathematical ...

Physical Review A, 2016 Given its importance to many other areas of physics, from condensed matter physics to thermodynamics, time-reversal symmetry has had relatively little influence on quantum information science. Here we develop a network-based picture of time-reversal theory, classifying Hamiltonians and quantum circuits as time-symmetric or not in terms of the elements ...

Quantum ultra-walks: Walks on a line with hierarchical spatial heterogeneity
Physical Review Research, 2020 We discuss the model of a one-dimensional, discrete-time walk on a line with spatial heterogeneity in the form of a variable set of ultrametric barriers.

Quantum walks, quantum gates, and quantum computers [PDF]
Physical Review A, 2007 The physics of quantum walks on graphs is formulated in Hamiltonian language, both for simple quantum walks and for composite walks, where extra discrete degrees of freedom live at each node of the graph. It is shown how to map between quantum walk Hamiltonians and Hamiltonians for qubit systems and quantum circuits; this is done for both a single- and

Quantum walk on a chimera graph
New Journal of Physics, 2018 We analyse a continuous-time quantum walk on a chimera graph, which is a graph of choice for designing quantum annealers, and we discover beautiful quantum walk features such as localization that starkly distinguishes classical from quantum behaviour ...

On the relationship between continuous- and discrete-time quantum walk [PDF]
, 2008 Quantum walk is one of the main tools for quantum algorithms. Defined by analogy to classical random walk, a quantum walk is a time-homogeneous quantum process on a graph. Both random and quantum walks can be defined either in continuous or discrete time.
