N00N states from a single non-linear directional coupler
Regina Kruse, Linda Sansoni, Sebastian Brauner +4
In the quest for applicable quantum information technology miniaturised, compact and scalable sources are of paramount importance. Here, we present the concept for the generation o…
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…
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…
Controlling quantum walks with coin eigenstates
Martin Stefanak, Igor Jex
The control of quantum walk is made particularly transparent when the initial state is expressed in terms of the eigenstates of the coin operator. We show that the group-velocity d…
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…
