Are right angles special? The optimal primitive reference frame
David Jennings
We consider the smallest possible directional reference frames allowed and determine the best one can ever do in preserving quantum information in various scenarios. We find that f…
Controlling qubit arrays with anisotropic XXZ Heisenberg interaction by acting on a single qubit
Rahel Heule, C. Bruder, Daniel Burgarth +1
We investigate anisotropic Heisenberg spin-1/2 chains with control fields acting on one of the end spins, with the aim of exploring local quantum control in arrays of interac…
Clique Graphs and Overlapping Communities
T. S. Evans
It is shown how to construct a clique graph in which properties of cliques of a fixed order in a given graph are represented by vertices in a weighted graph. Various definitions an…
Maximal-entropy random walks in complex networks with limited information
Roberta Sinatra, Jesús Gómez-Gardeñes, Renaud Lambiotte +2
Maximization of the entropy rate is an important issue to design diffusion processes aiming at a well-mixed state. We demonstrate that it is possible to construct maximal-entropy r…
Markovian Master Equations: A Critical Study
Ángel Rivas, A. Douglas K. Plato, Susana F. Huelga +1
We derive Markovian master equations of single and interacting harmonic systems in different scenarios, including strong internal coupling. By comparing the dynamics resulting from…
Exact mapping between system-reservoir quantum models and semi-infinite discrete chains using orthogonal polynomials
Alex W. Chin, Ángel Rivas, Susana F. Huelga +1
By using the properties of orthogonal polynomials, we present an exact unitary transformation that maps the Hamiltonian of a quantum system coupled linearly to a continuum of boson…
