Establishing the equivalence between Szegedy's and coined quantum walks using the staggered model
Renato Portugal
Coined Quantum Walks (QWs) are being used in many contexts with the goal of understanding quantum systems and building quantum algorithms for quantum computers. Alternative models…
The Staggered Quantum Walk Model
R. Portugal, R. A. M. Santos, T. D. Fernandes +1
There are at least three models of discrete-time quantum walks (QWs) on graphs currently under active development. In this work we focus on the equivalence of two of them, known as…
Moments of Coinless Quantum Walks on Lattices
Raqueline A. M. Santos, Renato Portugal, Stefan Boettcher
The properties of the coinless quantum walk model have not been as thoroughly analyzed as those of the coined model. Both evolve in discrete time steps but the former uses a smalle…
