Quantum walks with spatiotemporal fractal disorder
Marcelo A. Pires, Caio B. Naves, Diogo O. Soares-Pinto +1
We investigate the transport and entanglement properties exhibited by quantum walks with coin operators concatenated in a space-time fractal structure. Inspired by recent developme…
Quantum walks in two dimensions: controlling directional spreading with entangling coins and tunable disordered step operator
Caio B. Naves, Marcelo A. Pires, Diogo O. Soares-Pinto +1
We study a 2-D disordered time-discrete quantum walk based on 1-D `generalized elephant quantum walk' where an entangling coin operator is assumed and which paves the way to a new…
Enhancing entanglement with the generalized elephant quantum walk from localized and delocalized states
Caio B. Naves, Marcelo A. Pires, Diogo O. Soares-Pinto +1
Recently, it was introduced a generalization of a nonstandard step operator named the elephant quantum walk (EQW). With proper statistical distribution for the steps, that generali…
Negative correlations can play a positive role in disordered quantum walks
Marcelo A. Pires, Sílvio M. Duarte Queirós
We investigate the emerging properties of quantum walks with temporal disorder engineered from a binary Markov chain with tailored correlation, , and disorder strength, . We…
Quantum walks with sequential aperiodic jumps
Marcelo A. Pires, Sílvio M. Duarte Queirós
We analyze a set of discrete-time quantum walks for which the displacements on a chain follow binary aperiodic jumps according to three paradigmatic sequences: Fibonacci, Thue-Mors…
Multiple transitions between normal and hyperballistic diffusion in quantum walks with time-dependent jumps
Marcelo A. Pires, Giuseppe Di Molfetta, Sílvio M. Duarte Queirós
We extend to the gamut of functional forms of the probability distribution of the time-dependent step-length a previous model dubbed Elephant Quantum Walk, which considers a unifor…
