A classification of finite quantum kinematics
J. Tolar
Quantum mechanics in Hilbert spaces of finite dimension is reviewed from the number theoretic point of view. For composite numbers possible quantum kinematics are classifie…
Selective dynamical decoupling for quantum state transfer
Holger Frydrych, Antonín Hoskovec, Gernot Alber +1
State transfer across discrete quantum networks is one of the elementary tasks of quantum information processing. Its aim is the faithful placement of information into a specific p…
Driven Quantum Walks
Craig S. Hamilton, Regina Kruse, Linda Sansoni +2
In this letter we introduce the concept of a driven quantum walk. This work is motivated by recent theoretical and experimental progress that combines quantum walks and parametric…
On the Role of Information Theoretic Uncertainty Relations in Quantum Theory
Petr Jizba, Jacob A. Dunningham, Jaewoo Joo
Uncertainty relations based on information theory for both discrete and continuous distribution functions are briefly reviewed. We extend these results to account for (differential…
Discrete time quantum walks on percolation graphs
Bálint Kollár, Jaroslav Novotný, Tamás Kiss +1
Randomly breaking connections in a graph alters its transport properties, a model used to describe percolation. In the case of quantum walks, dynamic percolation graphs represent a…
Limit distributions of three-state quantum walks: the role of coin eigenstates
Martin Stefanak, Iva Bezdekova, Igor Jex
We analyze two families of three-state quantum walks which show the localization effect. We focus on the role of the initial coin state and its coherence in controlling the propert…
